Scale a tested physical paint recipe by mass or volume, or compare explicitly digital sRGB blends. Keep pigment mixtures, sample evidence and screen previews separate.
Choose your path
Scale tested physical paint ingredients separately from explicitly digital color interpolation.
Reproduce named paints and media on one measurement basis.
Enter measured sample amounts, target total and sample evidence; inspect each scaled ingredient.
No predicted physical color or mass-to-volume conversion is invented.
Distinguish encoded and linear-light sRGB.
Enter two opaque hex colors, switch interpolation space and compare the labeled swatches.
Does not mistake digital weights for pigment amounts.
Retain and correct a physical sample record.
Revise an ingredient, observe sample reference invalidation, recover inputs and download the source record.
Original recipe and mode-specific drafts remain inspectable without stale exports.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Measure individual paint faces with their own openings and coats. Compare product-specific volume ranges, real containers, matching stock and optional cost.
Professional color picker with HEX, RGB, and HSL conversion, WCAG contrast checking, and palette generation. Pick colors and copy CSS-ready values instantly.
Plan measured stain surfaces and pass-specific coverage ranges. Reconcile exact product stock, real containers and optional quotes without invented railing or stair factors.
Keep all sample and target amounts on one mass or volume basis. Include every paint and medium. Changing g to mL clears amounts rather than assuming equal density.
Ingredient amount = target ingredient total × sample ingredient ÷ sample totalEncoded-sRGB averages encoded channels. Linear-sRGB decodes, interpolates light values, and re-encodes. Both are digital operations, not pigment models.
Digital blend = interpolate A and B in the selected color spacePigment strength, opacity, substrate, medium and conditions affect physical appearance. A manually supplied screen reference documents a sample; it is not a prediction or proof of compatibility.
Exact materials + measured recipe + representative dried-sample recordUpdated: August 2026
Illustrative sample ingredients of 50 g, 30 g and 20 g scale to 125 g, 75 g and 50 g for a 250 g ingredient total. No physical color is inferred.
An equal encoded-sRGB blend of #FF0000 and #0000FF is #800080. Linear-light sRGB gives #BC00BC. Neither number predicts the mixture of red and blue paint.
Switching from grams to milliliters requires new measured amounts and source evidence. Different ingredient densities make a silent mass-to-volume conversion invalid.
Use recipe mode to scale named paints and media from an independently tested sample. Use digital mode to compare encoded or linear-light sRGB interpolation. Neither mode derives a physical mixing formula from RGB or guarantees a dried color match.
