Tags in different colours

Excuse my naivety and inexperience with flarum:

Been trying to set Tags in different colours, like the forum here.

So far can see I can use one in a custom colour and the rest are based on the faded version of the colour set in appearance!

How can I set Tags in different colours?

Hope my question makes sense! Thanks in advance!

consider this as answered :-) it was much easier than I thought :-)
