I was making a website for a client who runs a dryer vent cleaning service. I send over a nice draft with a side-bar navigation and a theme of neutral grays and greens.
Client: It’s all right, but I prefer the way you have your personal website with the bar on top. Could we do that?
Me: Sure! Anything else?
Client: Yeah, I hate the colors. Could you make it all in orange and blue?
Me: …Okay. That might be a little strong, honestly. Why are those the colors you want?
Client: I read online once that movie posters use orange and blue because they’re complementary. Just make it orange and blue, and change the layout to be more like your website!
I ended up just copying the template I made for my site and changing the colors to their liking. It looks terrible, but they love it.
