Remarks
The discontinuity in the C parameter at 0 means that floating point errors will often result in values near 0 giving unpredictable results. EG: 0.0000001 gives a very different result than -0.0000001 In cases where both a and b are very near zero this function will return an LCH color with an H of 0 More info about the atan2 function: https://en.wikipedia.org/wiki/Atan2
