Color Wheel
The Color Wheel is the most common way to select a color within TouchDraw. This color selection method consists of a Color Wheel for selecting an exact color hue and a Saturation Box for altering the lightness or darkness of a hue, as shown below.
To use the Color Wheel for making a color selection, press on the Wheel Button located under the Opacity Slider.
Tap on the desired hue in the Color Wheel and then tap on the desired lightness or darkness value in the Saturation Box.
