Today I recorded by fourth video on the Colourchat youtube channel. You can see the video here.

I started with a very difficult question – where is colour? – which ended up having to be recorded in two parts. So it was somewhat of a relief to record this easier question – is black a colour?

That said, there are those who argue black is not a colour. There are also those who argue that black is the absence of colour or even the absence of light. I briefly discuss all of these issues in my video.

In short, I think that black is a colour, albeit an achromatic one. It is definitely not a good idea to define black as the absence of colour of the absence of light. Anyway, watch the video if you are interested and let me know if you agree with my view.
