Is there a library to emulate color pallet selection?
What? 
Where would you want to display that color pallet given the Particles come without display?
@ScruffR, I think you misunderstood me. All I was looking for is color pattern setting values. example, for yellow, Pin D1,D2, D3 settings to be value X, Y, Z so that I can do a function call from my iPhone.
I do like the HEX way of writing color codes where two hex digits make up each base color ( 0x00RRGGBB ) and knowing that yellow is made up from equal intensities of red and green and no (or at least less) blue.
Also most graphic editors (even Windows Paint 
) do feature a color picker that gives you the R, G & B components.
But @MORA’s is a rather nice one 
sorry for the misunderstanding
