Certain color hues can be found at certain angles on the color palette. For instance, Red is 0 degrees (12 o'clock
position), Green is approx. 120 degrees (4 o'clock position) and Blue is approx. 240 degrees (8 o'clock position).
Secondary colors are Yellow at 60 degrees, Cyan at 180 degrees and Violet at 300 degrees.
The Luma value relates to how bright or dark the selected color or hue is. The Luma value can be adjusted using
