Anyone recommend any e number free food colourings please

Some e numbers make my throat swell up. Anyone recommend any good natural food colourings for icing.

Waitrose sells a packet contain 4 colours yellow green red and purple - they were bright and bland tasting. No blue though.

I don't think there are any e-number-free colourings. Cochineal (red/pink) food colouring, for example, is a natural extract which is E120. Annatto (yellow) is another natural extract E160b... but it can cause allergic reactions in some people. I think you'll have to isolate which dyes cause you a problem some other way than excluding e-numbers.

That's right, pretty much all colourings will have an E number, even if they're just things like Powdered Beetroot (E162), even the ones that don't (spinach powder will make a green for example) will simply not have an E number purely because they're commonly enough used.

I'm not sure there are any blues that are completely natural (as in sourced/refined/processed from a plant as opposed to made in a lab from chemicals which is presumably what you want.) However allergies are as likely to come from the refined plant material as the chemical anyway as cogito says.
