MUTED BLUE · CURATED PAINT RECIPE
How to mix slate blue
A gray blue for stone, distant landscape, metal, textiles, and cool architectural color.
STARTING MIX
4 : 2 : 1 : 0.25
Use one consistent unit for every part. For the smallest fractions, scale the entire recipe up instead of estimating a partial drop.
PIGMENT LOGIC
Why this mixture works
The ultramarine-umber pair creates a muted blue-gray. A smaller phthalo addition balances the violet tendency and keeps the result recognizably blue.
The displayed #64758C swatch is an sRGB target, not a promise that every brand will dry to the same color. Pigment identity, tint strength, opacity, medium, surface, and lighting remain part of the result.
BASIC-PALETTE ROUTE
Alternative recipe
Make a blue-biased chromatic gray from blue and brown, then tint it with white.
Apply the mixture on the same ground and at the same thickness planned for the final work. Label the wet ratio, wait for a complete dry-down, and compare in neutral light before adjusting.
CORRECTION MAP
How to adjust the result
Add blue for a clearer slate, umber for stone gray, or white for distant haze. Compare with neutral gray to judge the remaining blue.
Correct value first, then hue, then chroma. This order prevents a lightness error from turning into an unnecessarily complicated recipe.
WATCH FOR
Common mistakes
- Mixing black, white, and blue without checking undertone
- Adding orange too quickly
- Judging distance color beside a saturated palette only
