Complex to learn and worth the effort
To those who think this is another tap-to-color, READ the documentation. There is so much more to Colorest! You can shade a single color into light, medium and dark hues. Gradients are just long press and then swipe for linear or radial. Pencil mode is available, too. And then the magic brush! Creating your own multi-hued colors. You can tell it is much more than tap and color by looking at the user submissions. Some of these people are real artists! well, anyway I am a longtime fan and pay for premium just to support the creators of this app because I don't have time to color very often, but when i do, i want the best.
