Bought it last week in PartyZone, Jumeriah Beach Center (the one with the Automatic Restaurant). I think they also have a branch at Garhoud. I bought pink spray, they had a full range of colours.

Usually (in Oz) we can buy these at chemists. I have found in the past that the food colouring doesn't give as strong a colour and can run if kids are sweaty.
