Accessibility fedi, may I nerd snipe you a little. At the makerspace we have 9 doors. I'd like to repaint each door a unique colour, so we can have simple stuff like "lock on blue door broken" and remove ambiguity. Except, as xkcd has proven, colours are hard.

Is there a set of 9 (maybe 10 to allow for future expansion) unique colours that work with all colour blindnesses, and related visual accessibility needs?
