That's not what I mean^^. On Twitter, there are multiple artists who are posting their art with this thing. I wonder why.
Check out the link in the tweet. Its a cosmetic product promotion site, where you upload an image there, they will generate the colours of the cosmetic, just like in this pic. You can submit it into a competition or something, but I can read the rest. Probably someone found it, mess with it, and become a meme on twitter.
