Huh.... This is kinda fun. Being a synesthete myself, I think you got 6 (both times) and 8 all wrong :P However, we agree on 0, second 7 (only sometimes my 8 is reaching towards your 8 in colour) and while your 9 is yellow, mine is always orange. Still, pretty close. I read somewhere that there are no universal colours, but that many synesthetes have some general agreements. :)
for me 2 is blue and 3 is yellow
I usually picture text as my syntax highlighting does for my code editor.. Makes me wonder why "normal" books are so boring and lacking contextual info.
