Since 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'.
> myColors <- c(One="#FF7C00",Two="#00BF40",Three="#FFFF00")
> col2rgb(myColors)
One Two Three
red 255 0 255
green 124 191 255
blue 0 64 0
> rgb2hsv(col2rgb(myColors))
One Two Three
h 0.08104575 0.3891798 0.1666667
s 1.00000000 1.0000000 1.0000000
v 1.00000000 0.7490196 1.0000000
