WheelMasks 4+‎

WheelMasks is an utility to create harmonic color schemes that will help you improve your paintings and illustrations.

Create a wheel mask by drawing a shape over the color wheel that limits the palette of colors available for your illustration, providing you with an harmonic color scheme.

Unlike traditional palette creation apps, WheelMasks’ palettes are not limited to just a few colors, making it an ideal tool for the digital painter and colorist.

Use a preset mask or create new ones by transforming them or creating them from scratch. There are preset masks for the following color schemes: triad, square, tetradic, complementary, accent, split and analogous.

Configure the color wheel to your liking. Chose how many hues you want, how many levels for each hue and the brightness or, when available, the saturation.

You can see the color definitions, either as RGB values or Hex, in the extended palette view. You can also copy those values to the pasteboard.

- Choose from several color modes for the wheel: RGB, RYB, RYGB and Equiluminant.
- Keep an archive of the wheel masks you've created.
- Send your wheel masks to any image editing app that is capable of opening PNG files or export the swatches as an Adobe Swatch Exchange file or as Procreate's swatches.

All the modes but Equiluminant have three variants:

- Normal: a typical color wheel with saturation or brightness, you can choose, decreasing to the center of the wheel.
- Chroma: a color wheel with decreasing chroma to the center that keeps the same lightness in each hue, with lightness decreasing along the wheel from yellow to its opposite hue.
- Grey: a color wheel with colors converging to a neutral grey at the center.

The Equiluminant mode has two variants, HSLuv and HPLuv. The HSLuv color space is an extension of CIELUV, a color space that attempts perceptual uniformity. The lightness of every hue in the color wheel is perceptually the same, unlike the lightness of other color spaces which varies from hue to hue.
