... anyone else with the color problem
Would you be kind enough to get rid of your savedata and see if you still have the problem? You don't necessarily have to delete it, just like copy it somewhere else and have it not present when you boot the game so it makes a new save.
I have a suspicion it isn't properly importing the new initialization things ("you can use colors 1-10 for Squigly" etc) if you already have savedata.
The color pack will solve the problem but it needs to get fixed anyway.
Casino and Rooftops should unlock if you beat Squigly's story, and Glass Canopy should be always unlocked...?
Try getting rid of your savedata like I said at the top, boo. :^(
