Hi Martin, Great that you follow this. My original intention was to be able to translate colornames to hsv because this would allow using colornames to cut out a certain part of the colorwheel for colorcoding (HSV component H, see my code below) I think internally we might have colors represented as Colornames, ColorIntegers, ColorHexcodes, ColorRGBs, ColorHSVs (ColorCMYs?) however the R-user probably shouldn't see the internal ColorIntegers of the C-code, as this might lead to co...

...t users apply a ``gamma'' correction for their graphics displays. Most monitors produce a color intensity which is related to voltage by the equation intensity = voltage ^ gamma with gamma about 2.5 for most PC monitors. A typical symptom of this non-linearity is that a colorwheel produced by piechart(rep(1,48), col=48) shows a marked over representation of the red, green and blue and blue primaries. If this is the case try par(gamma=1/2.5) and redraw the color wheel. Vary gamma till you have a "nice" spectrum. This is experimental and feed...
