Expanding Color Controls
Sometimes you need precise numerical control over colors. You might also need to match
two colors exactly or adjust a color channel independently.
Every set of color controls has a disclosure triangle, which, when clicked, reveals sliders
for the Red, Green, and Blue color channels. You can choose or fine-tune a color by
adjusting these sliders. Among other uses, these controls are handy when you need to
keyframe each color channel differently. For more information on using sliders, see
