Colors can be trademarked in conjunction with certain services. Does this applies to UIs of computer programs as well?
Sure. Why would a computer UI be an exception? Law applies to computer interfaces the same way as it does to other things.
Trademarking colors is difficult though.
https://en.wikipedia.org/wiki/Colour_trade_markTldr: you can do it, but you have to argue real well that the color is distictive and associated exclusively with your brand.
An example of a trademarked color is ups brown
Violating copyright every time I take a shit
Fun fact: you can use most trademarked colors for anything as long as it isnt in the same sector as the company that trademarked it.
E.g, if a purse company trademarked a certain shade of pink, you could still sell computers that color.
Would I then run afoul if I branched out and had computer accessories, like laptop bags?
then the purse company would have to convince a court that the color of your laptop bag incites confusion as to wether or not they made it.
Not a lawyer, but hypothetically yes? I think it’s the same situation with Pantone colors being only legally viewable on Adobe software or whatever. (Will double check on the validity of that though)
So I can’t ship my shit?
Just don’t tell anyone, right? Mine is T-Mobile magenta.
To answer your unspoken question, yes, someone could have trademarked the yellow paint and stopped the madness right then and there.
I think UIs are more typically patented if they do something unique.
I’m pretty sure we know there are some trademarked UI elements though—I’d be surprised if the start button wasn’t a Microsoft trademark at least when they launched windows 95
