P&S: HELP! What color should I paint my room?

[I Am The Walrus]

I'm redoing my bedroom
I just came from having a disgusting Pepto-Bismol pink.. lol.. so gross.

I want to do it a buttery/pastel yellow, but my dad hates it.. lol
His words: "I hate it!..it looks like urine!"

Not doing it pink/black/white/brown
I was thinking maybe a light peach.

I want a pastel color.

Help?
Please & Thank you!
