FireColour is a very handy Colour Picker and Converter. Its already a part of FireCal. Its gives the colour values in 20 colour models. The conversions are now only for HEX, RGB and XYZ to 20 models. More conversions will be added soon. The colour picker component is a modified version of the RainbowPicker extension. All suggestions are welcome.
