It used to be in a variety of colours - but hasn't been manufactured now for several years.
The stuff I have is the 'natural' colour - which is a light beige/brown colour.
You can have it any colour you want - with some floor paint!
My boat has trac-mark covering beige - and it's painted grey. You have to use a very tiny amount of paint, and work it in the pattern of the diamonds, so brush at a 45degree angle one way, then opposite. You have to REALLY, REALLY scrub the paint out. It's better to do two coats, where the first is patchy - than try and do one generous coat.
Otherwise the paint fills the pattern.
