Behavior notes:
Radio buttons select "UseDefaultColors" vs. "UseCustomColors" modes.
If any color attribute is set in the body, mode is "Custom Colors",
even if 1 or more (but not all) are actually null (= "use default")
When in "Custom Colors" mode, all colors will be set on body tag,
even if they are just default colors, to assure compatible colors in page.
User cannot select "use default" for individual colors
