Colour Palette of the Month - March!

I was given this image by Wendy Freebourne, a talented knitware designer from Bath.

The colours are so warm and rich that I couldn't resist using them for this months colour palette.

So what dye extracts would you use for this palette?

I'd give the following extracts a try, from the top:
Black - indigo and an iron modifier.
Khaki green - kamala and a light dip in indigo.
Rust - sappenwood.
Beige - cutch.
Buff - himalayan rhubarb with a copper modifier.
