Description:

This function converts the specified color RGB percentages to hue, saturation, and lightness (HSL) values. (Note that HSL is not the same as HSB/HSV!)

All values except hue are in decimals between 0 and 1, inclusively. RGB values on the 0-255 scale must be divided by 255 before using them in this function.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

Discuss:

The example RGBtoHSL ( 1; 0; 0 ) returns "0¶?¶1".

The mistake is probably in the line 14:

sumC = maxC + maxC;

It should probably be:

sumC = maxC + minC;

Is that correct?

Yes, thanks, careless translation from Java. Edited.
