Reply to chroma caps or similar for my Allen and Heath xone 4D?

anyone know of any coloured caps that will fit on my Allen and Heath xone 4D?

my searching came up with mouser selling some caps http://uk.mouser.com/catalog/English/101/GBP/1815.pdf

but i was wondering about the chroma caps from djtt. they are much better colors

im from the uk if that makes a difference?
