Step 1: Convert volume to cubic yards (1 ft³ = 0.03704 yd³; 1 m³ = 1.30795 yd³)
Step 2: Total Cement (lb) = Cement per yd³ × Volume in yd³
(if cement given in kg/m³, convert: lb/yd³ = kg/m³ × 1.68556)
Step 3: Total Pigment (lb) = Total Cement (lb) × (Dosage % ÷ 100)
Step 4: Bags needed = CEIL(Total Pigment ÷ Bag size) — always round up
Step 5: Leftover = (Bags × Bag size) − Total Pigment
Industry standard: max dosage 7% for iron oxide; 10% for synthetic organics.
Dosage percentage is always by weight of cementitious materials (cement + SCMs).
How to Use This Concrete Pigment Calculator
Enter your total concrete volume.
Use the cubic yards figure from your concrete volume calculator — include any waste factor you've already added. If ordering ready-mix, this is the number on your delivery ticket. Select the right unit (cubic yards, cubic feet, or cubic meters) from the dropdown. Don't convert manually; the calculator handles it.
Enter the cement content of your mix design.
Your ready-mix supplier's mix design ticket shows the cement factor (commonly 470–658 lb/yd³ for residential work). If you don't have a ticket, use 564 lb/yd³ as a solid default for a standard 6-sack mix — it's the most common residential and commercial specification. For performance mixes with fly ash or slag, enter the total cementitious content, not just Portland cement.
Choose your color intensity (dosage rate).
Light tones like cream, buff, or pale terracotta use 1.5–3%. Mid-range colors like brick red, sage, or charcoal use 3–5%. Deep, saturated colors use 5–7%. Going above 7% produces almost no additional color gain and can affect workability and strength — most manufacturers print this warning on the bag.
Match the bag size to how you're buying pigment.
For small bagged-concrete jobs, 1 lb unit-dose packs are designed to mix with one 80 lb bag of concrete. For ready-mix deliveries, 10 lb, 25 lb, and 50 lb bulk bags are standard. Enter the retail price per pound if you want a material cost estimate. Round up to the next full bag — never split a bag mid-pour, as you can't guarantee consistent dosing.
⚠ Pro Tip: Always test your color on a mock sample slab using the same concrete mix, water-cement ratio, and finishing method before committing to a full pour. Final color is affected by water content, curing method, mix design, and the finish — a sample made at the plant will look different from a hand-mixed test at the hardware store. Once concrete is placed, the color cannot be adjusted.
Concrete Pigment Dosage Formula
Integral color pigment dosage is calculated as a percentage of the total cementitious material weight — not the volume of concrete. This is the industry standard method defined in ASTM C979 (Standard Specification for Pigments for Integrally Colored Concrete). Here is the step-by-step process:
Step
Formula
Example (5 yd³, 564 lb/yd³, 3%)
1. Total cement in pour
Volume (yd³) × Cement (lb/yd³)
5 × 564 = 2,820 lb cement
2. Pigment required
Total cement × (dosage % ÷ 100)
2,820 × 0.03 = 84.6 lb pigment
3. Bags to purchase (10 lb)
CEIL(pigment ÷ bag size)
CEIL(84.6 ÷ 10) = 9 bags
4. Leftover pigment
(Bags × bag size) − pigment
(9 × 10) − 84.6 = 5.4 lb unused

Which Dosage Rate Should I Use?
Dosage rate is the single most important decision in integral color work — it directly controls color depth, cost, and whether your final surface matches your sample. The guide below reflects standard industry practice for iron oxide pigments, the most widely used type for concrete.

Color expressed in finished concrete is also affected by water-cement ratio (lower w/c = richer color), finishing method (burnishing darkens; broom finish lightens), curing method (wet curing produces more uniform color than curing compound), and aggregate color. Two slabs at the same dosage can look noticeably different if poured on different days with different water additions.
Common Mistakes When Using Integral Concrete Pigment
💧
Adding extra water on the jobsite.
The single most common reason for inconsistent or washed-out color is drivers or workers adding water to stiff concrete after delivery. Every gallon of added water lightens the finished color and weakens the mix. Specify a plasticizer (water reducer) at the plant if workability is a concern — never add water at the truck.
📐
Calculating dosage based on concrete volume, not cement weight.
Pigment dosage is always a percentage of cementitious material weight — not cubic yards of concrete. A 5 yd³ pour with a lean 4-sack mix (376 lb/yd³) needs significantly less pigment than one with a 7-sack mix (658 lb/yd³), even though the volume is identical. Using volume as the base figure produces wrong results every time.
🎨
Skipping the test sample slab.
Pigment chips, color cards, and digital renderings are not reliable color guides. Finished color depends on your specific mix, aggregate, finishing method, and cure. Make a 2 ft × 2 ft test panel using the exact same materials before committing to a large pour. Let it cure for 28 days and apply your sealer before judging the final color.
🏗️
Ordering pigment in the wrong bag size for the application.
Unit-dose packs (1 lb) are designed for single bags of dry concrete mix. Using them for a ready-mix truck load requires dozens of packs and significant labor to add them. For any pour over 1 yd³, order bulk 25–50 lb bags that can be added directly to the drum or in the mixer at the plant — this is the only way to guarantee consistent distribution.
☀️
Ignoring the effect of curing and sealing on final color.
Freshly poured colored concrete looks very different from cured, sealed concrete. Applying a solvent-based or water-based sealer will noticeably deepen and enrich the color — sometimes by two or three shades. If your sample was made without sealer and you're planning to seal the finished job, expect the real slab to look significantly darker than the sample.
Frequently Asked Questions
Multiply your total concrete volume (in cubic yards) by the cement content per cubic yard (in pounds) to get total pounds of cement. Then multiply by your dosage percentage divided by 100. For example, 5 yd³ with 564 lb of cement per yard at 3% dosage = 5 × 564 × 0.03 = 84.6 lb of pigment. Divide by your bag size and round up to the next full bag. This calculator does all of that automatically — you just need to know your volume, cement factor, and target color intensity.
For standard iron oxide pigments, the practical range is 1.5% to 7% of cement weight. Light tints use 1.5–2%, medium colors (the most popular range for decorative work) use 3–5%, and deep saturated colors use 5–7%. Going above 7% produces almost no additional color and can slightly reduce compressive strength — most manufacturers' data sheets show a color saturation plateau at 6–7%. The exact percentage also depends on your aggregate color, water-cement ratio, and finishing method. Always make a test panel first.
Iron oxide pigments are the industry standard for integral concrete coloring. They are manufactured in yellow, red, brown, and black — blended to create the full range of concrete colors. Iron oxides are UV-stable, alkali-resistant (essential since concrete is highly alkaline), and do not fade over time. Synthetic iron oxides (produced chemically) are more consistent in color than natural oxides and are the preferred choice for commercial decorative work. Carbon black is used for very dark gray and black mixes. Chromium oxide produces greens. All pigments for concrete must comply with ASTM C979.
Properly specified integral color (iron oxide pigments per ASTM C979) does not fade — the pigment is dispersed throughout the full depth of the concrete and is UV-stable and alkali-resistant. What looks like fading is almost always one of three things: efflorescence (white calcium deposits migrating to the surface), surface carbonation (a light gray film from CO2 reacting with calcium hydroxide), or the original sealant wearing off and exposing a duller surface. Reapplying a quality penetrating or film-forming sealer typically restores the original appearance. Organic pigments and dyes have much lower UV resistance and will genuinely fade outdoors over 3–5 years.
Technically yes — pigment can be added to the drum at the jobsite — but it is not recommended for large pours and most ready-mix suppliers will not guarantee color uniformity if pigment is added after delivery. The preferred method is to have the pigment added at the plant during batching, where it can be dispersed with the full mixing action of the drum. If adding at the jobsite is unavoidable (for small touches or corrections), keep the drum turning at mixing speed for a minimum of 50–100 revolutions after adding pigment, and never split a bag across different loads.
Lower water-cement ratio produces richer, darker color. This happens because excess water dilutes the pigment concentration in the paste and creates more porosity — a more porous surface reflects more light and appears lighter. A mix designed at w/c = 0.40 will produce noticeably richer color than the same mix at w/c = 0.55. This is why adding water at the truck is so destructive to colored concrete quality — even a partial load of added water can visibly lighten the finished surface compared to sections placed earlier in the pour.
Integral color (this calculator) disperses pigment throughout the entire concrete mix, so the color runs through the full depth of the slab. Surface scratches, chips, and abrasion all reveal the same color underneath. Surface-applied methods include dry-shake hardeners (broadcast onto wet concrete), acid stains (react with calcium hydroxide to create translucent tones), and water-based stains or dyes (penetrate the surface). Surface methods give more vivid or variegated looks but can wear or chip to reveal gray concrete underneath. Integral color is more durable for high-traffic exterior applications; surface color offers more artistic options for interior decorative work.
Iron oxide pigments at dosages up to 6% of cement weight have a negligible effect on compressive strength — the data from major manufacturers shows less than 5% reduction at typical dosages. Above 7–10%, some studies show measurable strength reduction due to the pigment interfering with cement hydration. Carbon black is more sensitive — even at 3%, it can reduce strength by 10–15% if not properly accounted for in the mix design. For structural applications, always verify that the mix design has been adjusted to maintain the required PSI at your intended dosage rate. For typical decorative slabs, pigment at 3–5% is fully compatible with a 3,000–4,000 PSI specification.
Consistent color across multiple trucks requires three things: identical mix design on every load (same water-cement ratio, same cement content, same aggregate), same pigment batch from the same manufacturer (batch-to-batch variation is real — order all pigment at once from one lot), and identical water additions at the jobsite (which means none). Specify in writing to the ready-mix plant that no water additions are permitted at the drum without written authorization. Also, plan pour logistics so loads are placed quickly — concrete that sits in the drum too long before placement can have slightly different color than freshly delivered loads.
Iron oxide pigment costs vary widely by supplier and purchase volume. Retail bags at hardware stores typically run $1.80–$3.50 per pound. Contractor-grade bulk pricing from concrete suppliers is generally $0.90–$1.60 per pound. Premium synthetic oxides (more consistent, richer color) cost 20–40% more than standard grades. For a typical 5 yd³ colored driveway at 3% dosage, pigment adds roughly $150–$300 to material costs — a minor premium for a significant aesthetic improvement. Integral color is generally one of the most cost-effective ways to add value to a concrete project compared to stamping, staining, or overlays.
