For me, I’d say:
Math - yellow
English/ Literatures - red
Science - blue
Social Studies - orange
those are just the core subjects. I don’t think I associate any color for the extracurricular subjects like art or music – which of course you can add if you want.
For me, I’d say maths and Science are switched, and I’d associate purple with drama/theatre.
