Lighter Terracotta
#CD6D50
9 parts Titanium White, 5 parts Cadmium Red and 3 parts Burnt Umber. Chromilla's model predicts an 88% dry match against the target, scored against its own color model, not a measured paint-out.
To mix terracotta (#B25538) in acrylic, use 6 parts Raw Umber, 4 parts Titanium White and 3 parts Alizarin Crimson. Chromilla's model predicts a 90% dry match against the target, scored against its own color model, not a measured paint-out. Chromilla is a web-based paint color mixer that turns any color, from a photo, the camera or a hex code, into exact paint-tube ratios for acrylic, oil and watercolor, using Kubelka-Munk pigment mixing and aiming at the color after it dries.

Ratios calibrated for acrylic. Start with the dominant pigment, add the modifiers in the order below, and adjust in 5% steps to your target swatch.
1. Raw Umber
PBr7
2. Titanium White
PW6
3. Alizarin Crimson
PR83
Raw Umber, Titanium White, and Alizarin Crimson, in roughly a 45:31:24 ratio.
Start with Raw Umber at about 45% as your acrylic base, then work in Titanium White and Alizarin Crimson in the order above. Adjust in 5% steps until the swatch reads #B25538.
Mixing Terracotta yourself lets you approximate an expensive or hard to find tube from pigments you already own, match Terracotta across paint brands whose factory tubes differ, and rebuild the exact color when you run out mid painting. The recipe above is the working starting point.
White cools and chalks a mix as you add it, so tint in small steps and stop before it goes pastel.
Each variation is its own target (lighter and darker move OKLCH lightness by 0.08; warmer and cooler turn the hue 12 degrees toward red or blue), solved fresh.
