Yes, blue is nearly always the “favorite color” (Mine is orange, but I try to rise above it) but one thing that is impressed upon you fairly quickly when you’re designing interfaces is that nobody agrees what color is “blue”. I’ve spent hours and days with clients who were trying to agree on “Blue”. RGB, Pantone, CYMK, whatever, it doesn’t matter to the client. They want Blue, but that isn’t the Right Blue. I‘ve come to hate Blue with a passion, but I still spend an unconscionable amount of time with it.
P.s. I’m #ff7733 all the way.
