Where in the UK, can I buy a digital Radio with CD player in either hot pink or sunshine yellow?

Hmmm well unfotunately manufacturers tend not to be very adventurous with the colours of their equipment, usually its black or silver. However you could try http://www.aqdab.com/store/en/view_product/14/2316/
it’s a pink and black radio with a line in connection so you can play your MP3 player through it (or a portable CD player).
closest I think you’ll get i’m afraid.
