XF 2.0 How do you add a particular hex colour to the text colours

[Suzanne O]

Hey guys,

I've been asked a question as somebody on my forum loves using a particular colour of pink to type in.
Just looking for directions to where to add it to the text box that allows a certain amount of colours in it.
Also can that text colour box be changed to that rainbow slider thing like what we had in xf 1?

It's this colour we want.
(Hex #ff69b4)

Where do we add this colour?
