One of my in laws decided to redo their kitchen and they picked out a shade of yellow to paint it in. They then went away for a couple of days and my sibling was left to complete the task. Upon returning the kitchen was all done in a nice shade of school bus yellow, which was the color she had picked. They couldn’t blame my sibling either, since they are totally color blind and only see in shades of gray. Maybe they should have done a sample area before the whole room was completed. Though it would wake you up in the morning.
