I believe nowadays those colours would be referred to as "a choice".
The Big Breakfast had lots of merchandise. Not sure that stretched to electrical appliances, apart from the pink TVs they used to give away. I had a Big Breakfast bath set which had a bar of soap in the shape of a fried egg, a sponge in the shape of a slice of toast and bubble bath in a marmalade jar. I think there was also a shower gel you could get in a teapot shaped bottle too.
Wasn't there a Big Breakfast fruit machine too?
