I think I must have pressed a hot key combo by accident as all of a sudden all my colours became duller and less bright.
If I set them to their most brightest using the colour picker, nothing happens - they remain somewhat muted.
I've looked at a few other answers to similar to this and they suggest changing the colour settings. I've tried a few: Adobe RGB (1998), Apple RGB, sRGB, ProPhoto RGB, ColorMatch RGB, Monitor RGB, etc.
But none of them allow me to use the full range of hexidecimal values in the colour picker.
Can any one tell me what I've done and how to fix it?
What's the default meant to be?
