I am constantly changing colour.
I'm a rainbow if you like.
One minute I'll be doused in blue,
The next hidden in white.
I'm a chameleon of different coats,
Sometimes I go unseen.
Sometimes a striking ultraviolet,
Other times I'm green.
I don't think I have a favourite colour,
Although if I'm being true
I find I'm quite content as beige
And going unseen by you.
