They've added new colours through the years, however the accent colours the Xbox One had that went on to the newer gens (such because the Xbox web site and even the Collection consoles) are simply… bland. Nearly all of them look extraordinarily desaturated and lack vibrancy.
I've wished to make my UI and my profile yellow ever since I've seen this selection in 2015, however i couldn't. Gold/orangey was the closest possibility i bought.
Now, I'm not saying that they need to add each coloration I like (Everybody likes their very own colours, and a few would possibly say these are fully advantageous), however a coloration picker can be an excellent resolution to this. This shouldn't be that huge of a difficulty, Home windows already had this selection since 8.
