Material Colors
This pack contains 257 materials, which base colors have been selected in accordance with material design color palette guidelines(more info: Material Design).
I’ve done this for myself, to increase speed of level prototyping(it’s easy to mark different functional areas of level with different colors and it would be nice if colors will be nice 
) and now want to share this with you.
I know, it’s not a big project. But I hope you’ll find it useful for yourself.
