Not at night.

Do things lose their colour when there is no light?
Yes.


So what colour is a blue football in a dark room?

It has no colour - which we call black.

There's no such thing as colour it's all a visual representation of the wavelenght of the light we see, and how we divide it up in order to describe it.
A bit like Bass, middle and treble in audio, colours are just a useful way of describing what we see.

There's no such thing as reality. Just a description.

Perception shurely?

Yes, perception is a description, if anything is perceived.

One can perceive things without describing them...
