Personally I like the cyan you used. With regard to the image in post #22 I was just trying to show how the original looked and you are correct it still as the four colour fill, all I did was remove the black background and select the entire diamond and gave it a luminosity fill to look more like the original so the four fills look like shades now complete with lines I added which the original had. The postage stamp size original, I do not have any longer.
