Where to buy brightly coloured marshmallows ?

[londondee]

Hi mumsnet bakers! I'm trying to get some lightly different ingredients for making rocky road. I saw some at a local food fair with bright pink and bright blue / turquoise marshmallows but the woman selling them was reluctant to let me know her source ... had anyone seen something like this for sale? Thanks

Amazon seems to sell them.

I've dyed them using gel food colouring before - it wasn't very very bright but they looked good. And you can dip dye if you want them striped. It's only the surface though. Alternatively marshmallow isn't hugely difficult to make.
