Yellow bathroom yes or no?

I’ve been thinking about painting the schoolhouse bathroom yellow.

This would a quick and easy solution to its current bachelor board look and may brighten up the one room that has no windows.

I thought it might be cheery but all of the selections on Pinterest are paired with grey. I think that is weird. What does everyone else think?

Or I could just do this for fun?
