Eggs-actly that. One of the things about egg tempera is making a
lasting pigment out of available resources so mixing it up is just a
matter of following an easy recipe using common things as people have
done for centuries. You've probably already got everything you need.

www.kremer-pigmente.com

sells pigments, dry, with suitability for various binders inluding egg tempera
listed. The most reasonable are a few Euros/quid for a pile, often 100g. They'll
mail to the UK, and there's a UK distributor.

They live off collecting things that are common, but maybe in common in far-off
places, and then selling them. Or things that were once common, like lampblack,
or just finding colorful rocks and ball-milling and sieving them...
