Natural Colourants

I posted another one a while back, but this one looks clearer.

Nice.

I am surprised that the Turmeric is so pale. I did that a couple times and it was darker.

The paprika is lovely, I need to infuse some and try for something similar. Thanks for the post @Relle

I need to try woad!

I really wish I could get my hands on woad or purple Brazilian clay....

Woad is on my try list too.

I assumed that clays and AC wouldn't change coloring over time. Only plant based colorants would. Is this a safe assumption?

My woad is never that dark. I usually get a lighter blue color. I need to get some other clays for a lighter color.

That is generally true - clay and charcoal don't usually fade. Some natural colourants fade a lot, but some stick around for a long time.
I've got a 10 year old paprika soap that is still an orangey-red colour, and coloidal oatmeal will stay a creamy colour (as two ends of the scale).

Just about any chlorophyll based colour (plant green) will turn brown over time.

Cocoa and coffee don't tend to fade much. Poppy seeds don't change colour.

A lot of natural purples tend to go brown like greens do. Lavender always turns brown.
