Where is that comic about standards now that we need it? The one where they create a new standard that is going to solve all the problems, except for now there is just one more standard??

Good question, I think this one is called Bob, but it could be his brother Frank too.

Darker colors make it more cozy. Light colors make it feel more like a hospital. Green, brown, sand colors, dark blue, dark grey maybe. Just slam something on the wall and check how it feels. You can always paint it again.
