SEGA, stop forcing players to use Chalk skin in Lessons

Chalk skin is a horrible skin if you are colorblind (like me). And the fact that you HAVE to use it in lessons mode is just a nuisance for those with disabilities, even if the Puyo Puyo Tetris 2 and Puyo Puyo e-Sports both have colorblind settings, the fact that the chalk puyo don't connect still makes it impossible for some people to play with them.
Sega, please give people the option to use a more friendly skin for Puyo.
