The palette is the tileset colours that i posted.
Do you want a labeling system for each colour so we can keep accurate count?
I can't guarantee the precise shade of colours but we can approximate closely enough i think.
At the shop i noted all the colours to make sure we werent missing anything important and i'd just label them as <colour> followed by D for dark, L for light, and if a third shade vD for very dark, vL for very light. This is pretty easy for anyone else to apply and likely match up with someone else.
We can mark the colours as follows:
D = Dark vD = Very Dark
L = light vL = Very Light
Yellow D, L
Red D, L
White
Green vD, D, L
Black
Grey D, L
Purple D, L, vL
Pink D, L
Brown D, L, vL
Blue D, L, vL
Orange D, L
Aqua/greenblue D, L
