Artoonix - dissolving colours - tutorial

Kaynine says "Instead of the type of tutorial where text is typed in and then erased and new text appears, I've focused on the main steps in the process of tweening colours. Blocks of text explain what's happening. This way, I hope I've explained the process without needing you to sit through page after page of typed and deleted text. I've completely given up asking for feedback into the Artoonix forum (why isn't anybody participating ?????). So if this is useful - or if it isn't - please add a comment. Somewhere there are a lot of Artoonix users who seem to want to have no input into the forum - which makes SUCH a difference to virtually all the other examples of animation forums out there.Can anybody explain ?"
