The change in tint for yellow belt, by itself is nice. But not as much when attaching yellow splitters and underground belts.
Would it be possible to either change the color for them to match, or offer the belts with the normal yellow color as an option?

I think i know what you mean - the mismatch of colors.
I like the richer yellow, but i think the best decision here is to stick to the original scheme.
I will match colors on all belts closer to splitters and underground belts, thank you for pointing it out.

To me, this update looks better. Thank you!

I like this mod, but the colours are not identical with Loaders and other logistic buildings wich uses vanilla colors.

Loaders? Logistic buildings? Can you be more specific?
Belt colors in original scheme are color picked from underground belt covers, and match it and splitters in hue, but are a bit more washed out, to tone it down.
It still matches the original belt scheme overall. If you mean that inserters dont match, they don't match splitters and underground belts either in the base game. I made a choice for the belt line in the original scheme to be toned down, because the main point of the mod is to make the belts less distracting.

I mean Loaders, not splitters, not underground belts, LOADERS. the collor is to washed out even compared to vanilla ones,
I mean i like it but it is only belt, it needs same colour for splitter, underground belts and loaders, compact loaders.

This mod got nice colors for belts and everything, and High Quality too.

LOADERS? Sorry didnt hear that, LOADERS you say?
I will adjust the color to be slightly closer to vanilla splitters and underground belts, as other people expressed that its too washed out, but i don't use LOADERS, and mods that include LOADERS, but, you are free to fork and adjust the mod to the LOADERS.
The mods you linked, one has colors completely mismatching vanilla colors, and another is for 0.17 from 6 years ago, even on preview you can see the old splitters that had different color.

Thousant appologies mate, did not meant to offend anyone, but i misstyped wrong mod, well the Confortable Loader indeed has wrong color because i was using Neon belts mod and did not know how the vanilla belts color looked like, i uninstalled neon belts and now see the difference.

I am using AAI-Loaders by Earendel, if i could get the color graph for the Vivid colors from your mod maybe i can color the AAI-Loaders to have the same color,

One of this pipettes would be nice for all 4 belts

Vivid Colors -- if you can make AAI Loader to match would be Awesome!!!

Vanilla Colors

Maybe you can code the color inside your mod for AAI_Loaders also if the mod exists along with your mod.

Please check the new version, read changelog!
As for the color picker option - apart from me having no experience in doing this, currently the coloring process involves a bunch of painstakingly created vector masks, gradients and shadows, and what's more important, the use of specific layer modes (like overlay/screen) where necessary. I will look into it later, but to my knowledge most often in game masks work on a simple multiply mode which doesn't leave much room for subtle color, and is limiting. So, maybe.

Nice Touch job well done

Nice work with the thin line now we can see belt color anytime. cause the thin line is in the middle.

Now next improvment is to make line glow in night time but that is a good dream.

I think if you fill the green belt completely, it won't be clear which way it goes, because the colored stripe is only in the middle.
