David, >> I hope someone else can offer better advice… << That's pretty good if you have to eyeball it, there is a formula for checking RGB against composite and since you asked I'll pass it along. Composite RGB Y (.299 .587 .144) R I (.596 -.274 -.322) G Q (.211 -.523 .312) B _________ Saturation = V 2 2 That's supposed to represent the square root I + Q of I squared plus Q squared. Not a perfect medium to express this formulas. Maybe R5 will allow you to create or have custom palettes so that any color used within the palette will be NTSC or YUV safe… wish list item. John
