For many purposes the exact amount of colors doesn't matter no. Here at PJ in our search for a fitting definition of pixel art for the site we've decided that control over the palette is a requirement for submissions, see rule 4 on the submission page.
I'm looking forward to see the cleaned up versions of the 4 icons, they look great otherwise :)
Thanks, pretty new to all this, I will get it fixed. The engine I'm making these for doesn't require a reduced color palette. Not an issue if I need to conform to a limited number of colors though?
Something has gone wrong with the colors on this one, there are 508 of them and a bunch are semi-transparent. Can you fix that? Thanks!
