About Chromilla
The color toolkit painters actually wanted.
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. Around it sit tools for planning a painting from a photo, building and calibrating your palette, daily mixing practice, and running classes.
How the mixing works, and how accurate it is: the science behind Chromilla.
Questions
- What is Chromilla?
- 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. Around it sit tools for planning a painting from a photo, building and calibrating your palette, daily mixing practice, and running classes.
- Why use pigment-based recipes instead of a digital color picker?
- Screens use additive RGB light, but paint mixes subtractively. A hex value tells you what a color looks like on a screen, not how to make it from tubes. Chromilla converts the target into a pigment mix that behaves correctly when wet paint meets wet paint.
- Which paint media does Chromilla support?
- Acrylic, oil, and watercolor. Each medium comes with mixing tips tailored to how that paint behaves on the palette.
Chromilla is a color mixer made for painters. Drop in any color, from a photo, a hex code, or straight from your camera, and we turn it into a clean recipe of real tubes you can squeeze onto your palette.
Why a hex code isn’t enough
Your screen makes color by adding red, green and blue light. Paint does the opposite. Pigments subtract wavelengths from the light bouncing off the canvas. That’s why a hex code looks gorgeous on a monitor but tells you nothing about which tubes to squeeze.
Chromilla closes that gap. We model how real paint behaves on a palette, so the recipe you get is one you can actually mix, not a screen-perfect color that’s impossible to reproduce in oil or acrylic.
Real tubes, not theory
Every recipe uses paints most artists already own. No obscure pigments, no chemistry homework.
Tuned to your medium
Acrylic, oil and watercolor each behave differently. Chromilla adjusts the mixing tips to match what you’re painting with.
Match anything in sight
A reference photo, a paint chip, or that exact sunset. Snap it with your camera, sample it from an image, or paste a hex.
Less paint in the bin
Clear proportions mean fewer muddy mixes and a lot less paint wiped away while you chase a color.
Who paints with Chromilla
Hobby painters chasing a skin tone. Studio artists matching a client brief. Students learning how primaries actually behave. Miniature painters matching a discontinued pot. Teachers running a sip and paint. Anyone who’s ever stared at a tube wondering “okay, but what do I add to fix this?”
