The mouse only has and can only change the colour 7 breath by breath, e.g. you can't change the colour you want.

I wish I knew, unfortunately I didn't have a mouse with me.
I only wanted the keyboard, so I didn't care.
But I would say no, with the keyboard there are also only 3 settings: rainbow blue - green - yellow
or green red blue or no illumination the colours are also fixed and do not change.
