WheelMasks: Harmonic Colors

By Roger Tallada Solano

Open iTunes to buy and download apps.


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.

A one time In-App purchase enables WheelMasks' full functionality:

- 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, HUSL and HUSLp. The HUSL 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.

What's New in Version 1.0.5

Added an option to export all colors at once to a Procreate palettes file when there are more than 30 colors selected. When opened in Procreate they will be split in palettes of 30 colors as before but you won't have to export each palette individually.

If you enjoy using WheelMasks, please consider rating it on the App Store, thanks! :)

Best Color Palettes Ever!!!

The range of Colors and the ability to create custom pallets that can be used with the top Creation apps such as Procreate and Concepts makes this App Simply the Best. If you like the idea of creating palettes that can be given custom names and stored for future projects without having to write down the mapped color numbers for each custom color and like the idea of having specific palettes for each of your custom collections; then this is the app for you.

The Best

After only 5 minutes, I can say without doubt that this is the best color picker / color harmony tool on the App Store. This tool does more than any other I've found for creating color harmonies. The interface is decent, it has a tutorial/built-in help, and it can export a color palette directly into Procreate. My search (and it was a long one) for a color harmony app on my iPad Pro stops here. It's time to go make some art!

A wonderful addition to the artists's selection

I began looking for a gamut/yurmby color wheel after reading James Gurney's "Color and Light" and this has thus fare been a worthy tool in the search for the perfect color schemes for an illustrative painting. I have already recommended to friends and shall continue to do so!
