I need to stop editing my posts, by the time I've updated it you've responded xD

And honestly the rolling is an interesting idea, and it's leagues better than the "here's your character, here's their personality and history and PLAY THEM EXACTLY LIKE THIS" that I've seen some other (crappy) RPs do. You might have a better batting average of people getting character prompts that they enjoy if you explain the categories a little bit more though—not saying to give full explanations, just something. Would help with stuff that's super subjective, like the meaning of colours. For me, green is a colour of wild impulse and freedom, since I grew up in a forest. I very much don't associate it with anything medical or support related, so for me that link kinda felt like it came out of left field.

And yeah, I'd be happy to do an RP with you sometime, either group or just one on one! Let me know if you do another one of these category roll ones too, now that I understand your metrics a bit better I think I'm less likely to get saddled with a prompt I dislike :P

If you're interested in a one on one, here's a link to my search thread:
