Masstone
Color mixing helper
$8.99
Are you an aspiring artist?
Do you struggle with mixing colors?
Masstone turns a color into a paint mixing recipe: which tubes, and how much, from the paints you already own.
Give it the color you're after (pick it out of a reference photograph, or just select it from a color picker) and it will give you a recipe you can act on (ex: 2 parts Titanium White, 1 part Ultramarine Blue, 1 part Alizarin Crimson)
The hard part was never seeing the color. It's knowing which colors to mix on the palette to get there.
REAL COLOR MIXING, NOT RGB AVERAGING
Screen color is additive; paint is subtractive. Blend blue and yellow as pixels and you get grey. Masstone never averages RGB. Every mix runs through spectral reflectance curves, so blue and yellow make green, as they do on your palette.
BUILT AROUND YOUR PAINT BOX
- Set which tubes you own. Recipes are searched only from those.
- Star your go-to paints and the search leans toward them.
- Set a paint aside to ask "what would this look like without the Cadmium?"
WHAT YOU GET FOR EVERY COLOR
- The mix, in whole parts you can measure with a knife.
- Step-by-step mixing instructions showing the pile's color at each stage.
- Alternative recipes.
- A warning when a strong tinter is about to run away with the mix.
- Pigment sheets: tinting strength, color index, and what to substitute if you don't have it.
MORE
- Pin colors and compare them side by side. See what they share, where they diverge.
- Pick a color without a photo, from a wheel or a hex value.
- Acrylic mode shows both the dry color (what has to match) and the wet color (what should be on your palette).
- Sample history for the last few picks.
IMPORTANT NOTE
This is a mixing aid for painters, not a laboratory instrument. Lighting, camera white balance and your own brand of paint all change the outcome. What matters is which pigments to reach for and roughly in what proportion.
Made by an oil painter who kept mixing mud.
