4 years ago I also can't seem to input full 6-digit hex colour codes when typing in the colour picker box, as typing three digits accepts it as a the 3-digit version (e.g. #123 becomes #112233). You can still paste in full 6-digit codes and have the box accept them.
Would be good if the colours chosen to represent new cells didn't clash with ones that already exist, as I managed to confuse myself by creating a diagram where several elements were all the same colour and I couldn't distinguish between them! Maybe even have an option to forbid the selection of colours manually if it already exists in the diagram (although for complicated diagrams you might have to double up at some point).
Also more colour presets would be nice!
