Calculation example: R 30 -> Hue 200° -> 200 / 360 * 255 = 141.67 -> 142 G 50 -> Saturation 33% -> 33 / 100 * 255 = 84.15 -> 85 B 60 -> Lightness 18% -> 18 / 100 * 255 = 45.9 -> 45
Please note that the Hue on the web page uses degrees ('°') - i.e. 360° for the full range of color hues.
AFAICT there is nothing wrong with Inkscape's calcuations (there might be differences how the values are rounded in the GUI).
