Well for pinks and purples those colors will always use red and blue at different intensities. I don't have any color charts that have values for those but if you download the micro wash pdf user manual there is a color chart in there to help you mix some colors. But for pink and purple you will just have to plat around with the blue and red channels also try adding a little bit of green to help make the color. But to really get a nice dark purple and pink you proably need a fixture with RGBW or RGBA. The W is White the A is amber. The combination of these two colors on a led unit provide a much much more versatile fixture in color mixing. Hope this helps.
