Hm...,
Should these two versions produce the same solution? Unfortunately and
shame to confess, I don't know much about the colors in R:
myColors <- c("#FF7C00","#00BF40","#FFFF00")
Colors=rgb2hsv(col2rgb(myColors))
apply(Colors,1,mean)
h s v
0.2122974 1.0000000 0.9163399

# Average the 1st two by taking the middle colour of a 3 colour palette
x <- colorRampPalette(c("#FF7C00","#00BF40"), sp...

...these are color strings, you can use functions in the grDevices
package (other others) to manipulate them. E.g., you can convert them
to various color spaces and perhaps use the mean in one of those
spaces as your 'average color'.
