The other revelation of the colour palettes has been leaves green leaves using transmitted light. We normally look at leaves in reflected light, but transmitted light is when the light source shines through the leaf. Your reaction is to think they are just shades of green, but they are much more complex than that.
On my walk yesterday The Doc picked up some eucalyptus leaves which he identified as Eucalyptus baueriana, or Blue Box. The Doc found an immature leaf and a mature leaf and photographed both.
Here is the immature leaf, a fairly consistent green.

The palette reveals it is more complex 154 core colours!

The mature leaf has core colour palette with 254 colours, 100 more!

The Doc then took both images and looked at the combined colour palette from both, it was 242 colours. While there is an overlap in the colours, the various palettes demonstrate that the leaf over it life varies in colour. More than what we first think. The Doc noticed this in barks as well and it is obvious over the life of flower.
