I thought the same, actually I only have the yellow one (turmeric, of course, that brilliant color…) because I made experiments at Easter… I usually only have the brown ones (balsamic vinegar and optionally soy sauce as well). At Easter, I used onion peels too but on eggs with their shells on… No photo because I wasn’t very pleased with the results, they were pretty but the color came off too easily and the result color wasn’t as pretty. I still couldn’t shot it but I barely never did photos back then, now I surely would grab my camera and do something with whatever eggs I have!
I will make more experiments in the future. I want blue eggs too. And of course, the wonderful ones with beetroot and too much patience I am not sure I possess… The brown and yellow ones are pretty nice in a single day… I eat my eggs too quickly 
@OgreZed: Bread is very delicious to me… Well, it depends on the bread. And some rice is flavorful too (like Jasmine), the normal one is a bit bland, yes, I don’t miss it at all and never was a big fan. Pasta is tasty if it’s full with good eggs…
