v4
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.

リリースノート

v6
Bugs Squished on out-of-boundaries input values.

リリースノート

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 :)

リリースノート

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.

リリースノート

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

thanks @NeonTL8

リリースノート

v11
update small to fix an otherwise non-noticed brightness glitch

リリースノート

v14

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

リリースノート

v15

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

リリースノート

v16

Faster. Way faster.

リリースノート

v17

Optimized a bunch, Fast as i can get it.
