Oil and Crawla share some things with my own color pack (Oil having a similar palette to Eggman's Trap and Crawla sharing a name), and Motobug can CERTAINLY be improved.
Certain colors are also stolen from different sources (S&K being shared on the Discord server as one of the colors for the Mega Paint Drive, and Rainbow being the literal trademark color of SCCSCC - you even used its icon!)
Otherwise, welcome to the SRB2 modding community, and man those are some nice colors.
