The thing is no one ever uses one of these pallets. You start off with one maybe as a base and then adjust everything to get stuff just right. The Coolors UI seems to be good at that.
I love coolors. Just hit space bar to cycle. Once I see a color I like, I just lock that color and continue hitting space bar and locking colors till I have a full pallet :-)
This was very neat. What I'm about to say should not detract from that – this is probably one of the better palette tools I have used, if not the best.
But why on Earth would you want a user account and cloud storage for 15 bytes of colour values?
