Google Apps Script Color Space Conversions.

In Google Apps Script Color functions I introduced a bunch of functions to manipulate various color spaces from GAS. This was a migration from the same thing in VBA.

I extended this to include additional color spaces such as Hsl, hsv, Lch, Lab amongst others in VBA from which you can generate a selection of color palettes.  Here’s the Google Apps Script version. This extensive library of color conversions are available in this shared GAS library. I must admit I found the math a little trickier in the GAS version.

5 color pallete

Here’s some random colors and their 5 step palettes generated in GAS according to hue, lightness and saturation using the HSL and CIE-Lch color spaces.

Here’s the code to create these random palettes. You can find the whole thing in this workbook which also uses this shared GAS library

(function() {
var po = document.createElement(‘script’); po.type = ‘text/javascript’; po.async = true;
po.src = ‘’;
var s = document.getElementsByTagName(‘script’)[0]; s.parentNode.insertBefore(po, s);
