The Tamarind is a tropical tree with a fruit that is used in foods from spicy to sweet. You might have encountered it in a dish of Pad Thai.
This CiM Tamarind is a warm brown, a real, soft mocha colour. It's streaky, and doesn't appear to react with ivory.
This looks like another great, organic color, good for natural stuff, trees, horses, dogs, etc.
A nice warm, toasty color.
