animation question

[Kate McMillan]

I've been playing around with animating a simple gif.

Very simple. http://www.katewerk.com/images/pissoff3_animate.gif

Question is this - I would like to add some more color, now that my first
little experiment is a success. But I cannot seem to figure out how to go
back into the layers to bring them up for editing?

I must be missing something obvious.

(like rtfm.)
