UPDATED
Rewrote HSL chain and fixed problems with out of limit values
should be bulletproofed now and is faster than it was

thanks @NeonTL8 for notifying me of the problem.

Notas de Lançamento:
v6
Bugs Squished on out-of-boundaries input values.
Notas de Lançamento:
v7

For those interested in the color math, renamed all variables.
minified version available if requested/required

Also moved gradient calc to function from calc library,
on 0 distance between start and end it will default to first color.
i suggest iff you want to maintain on cross, use this:
abbv versio:
var _col
....
_col := switch
    _start ==  _end => _col
    => h.....(gradient here w/ start and end)

Have an indicator you wish to style? send me a message :)
Notas de Lançamento:
v8

Added two Helpful tools for creating multileveled colors

Current (nov 2022) Demo image is 100% original non-standard indicators, an same script with different sources and parameters..

built minimal using these two new tools, and 8 fills with 9colors each layer fades to a gradient of the last.

Notas de Lançamento:
v10
fixed bug on crossing end of gradient value and beginning value which caused hue glitch.

thanks @NeonTL8
Notas de Lançamento:
v11
update small to fix an otherwise non-noticed brightness glitch

Notas de Lançamento:
v14

Sorry! accidental wrong version published ..
upgrades and nitpick fixes (0 hue transp cols)
Notas de Lançamento:
v15

for found bug on pinned values on gradients when past limits and saturation is 0 on one and full on other.
