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.

Notes de version
v6
Bugs Squished on out-of-boundaries input values.
Notes de version
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:
Pine Script®
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 :)

Notes de version
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.

v8
Notes de version
v10
fixed bug on crossing end of gradient value and beginning value which caused hue glitch.

thanks @NeonTL8
Notes de version
v11
update small to fix an otherwise non-noticed brightness glitch

snapshot
Notes de version
v14

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

for found bug on pinned values on gradients when past limits and saturation is 0 on one and full on other.
Notes de version
v16


Faster. Way faster.
Notes de version
v17

Optimized a bunch, Fast as i can get it.
