James, we need to know more about what system you are using,
ie
substrate, dope or ?
color dope or"?
how long has it been since you cleared it?
How far into the color did you sand? all the way to the base?
Randy Powell is probably as knowledgable with mixed systems as anyone that I know, perhaps he will weigh in for you

If it is a base clear system, color auto base, and urethane clear, you can recoat when the clear is cured, usually about 24 hours,,
if you have laquer or dope color,, well you are going to have to be very gentle, especially with the color as any build up of solvents has the tendancy to creap back under the edge of the clear and it will swell and lift the clear, just like paint stripper.....
hence why I dont advocate dope color and urethane clear,,

Oh Randy,, jump in here
