In my previous life I used to be a straight man

I don’t get colors. I know yellow isn’t good for my complexion. And green makes me look like seriously seasick. But what comes to what shade of red our livingroom walls should be, I’ve no idea. I like the color we have now. Apparently it’s too dark. So if it’s too dark the obvious solution would be painting it a lighter shade of red. But no. Instead I’m looking at samples of yellow. Wtf.
