Hi Tasha, I may be right off the track, but you could plot RGB proportions on a 3D plot. The easiest way I can think if would be to convert your 0-255 values to proportions:
rgb_prop<-read.table(text="Red Green Blue pct 249 158 37 56.311 249 158 68 4.319 249 158 98 0.058 249 128 7 13.965 249 128 37 12.87 188 128 37 0.029 249 128 68 0.161 188 128 68 0.015 188 98 7 0.029 219 128 7 2.773 219 128 37 2.583 188 98 68 0.058 219 128 68 0.525 249 188 37 0.876 249 188 68 1.08 219 98 7 0.482 249 188 98 0.015 249 158 7 3.852",header=TRUE) rgb_prop$Red<-rgb_prop$Red/255 rgb_prop$Green<-rgb_prop$Green/255 rgb_prop$Blue<-rgb_prop$Blue/255 library(scatterplot3d) scatterplot3d(rgb_prop[,1:3],cex.symbols=sqrt(rgb_prop[,4]), color=rgb(rgb_prop[,1],rgb_prop[,2],rgb_prop[,3]),pch=19) then plot the RGB values on a 3D scatterplot. I have included arguments to make the symbols the actual RGB colors that you specify and their size proportional to the square root of the percentages.
