I find there are some good alternatives to coloring your dishes, Turmeric & a little Tomato Puree work well, I'm definitely not PC but do tend to lean to substituting chemical color with more natural colors & on top of that it is a challenge to be able to do so & lets face it everyone, we here at cr0 are up for a challenge,

it may be a good idea to have that in hints & tips (Natural Alternatives to chemical colors & a not so natural Colorings used sections).
One point on the PC side of things, following the normal path (horrible word) & using colors is far more PC than finding Healthy Alternatives to what Normal (AAAAAHH) people do! IMHO.
But thats my opinion & I'm only barely Human, thank Satan & all his Hellish instruments of PaIN ;D
Down with being a Sheep ;D
A Pirates life for me yo ho yo ho ;D
