Perhaps later in say, ToL 2.0 you could add more death note colors, either as a in game purchase cosmetic type thing, or free.
But only natural colors. Like green would be Grinder leaves, brown would be 
, blue made from ink berries. And things as such, or perhaps a class named Mad Artist or something, that has access to numerous colors and kills people just to publish art, now that’s passion.
Anywho, that’s my idea for a color expansion, but I like my Mad Artist idea better than paying for colors or them being free, a role with Rainbow access
