I use TJ's custom character,
https://mods.factorio.com/mod/TjCustomPlayer

Then create my own, it look like this :

To retain character color, i set color to black with zero alpha
/color 0 0 0 0

Problem was, ChunkyChunk is also gone with that command

I can set it to /color 127 127 127 100, my character is slightly brighter, i'm okay with that. But ChunkyChunk becoming white lines.

I really like the original player vanilla color, that yellow/orange lines that ChunkyChunk use.
I wish i can set it independently from my character player.

I could force the alpha of the ChunkyChunks colour to always be 100% as a simple fix to start with. So you can use 0 alpha for your character but still get visible lines.

I'll qonsider making line colour separate from character colour if that isn't enough.

ChynkyChunks v1.0.3 now always has 100% alpha regardless of the player character colour as a quick fix for now.

It would be possible to have a slider\color palette on mod's settings to manage it independently from player? And differs between grid 1 and 2

Due to popular demand, it's now possible to specify grid colours in settings in ChunkyChunks v1.0.4!

It would be possible to have a slider\color palette on mod's settings to manage it independently from player?

Sliders and palette selector are impossible in mod settings menu. But it's possible with a colour string.

And differs between grid 1 and 2

Yes.

Thanks for the new features !
Question regarding color input, "range from 0-1"
Was that an equivalent of max RGB color ? Or does it mean accept a decimal value ?
Like in the given example of Red being 1 0 0 is the equivalent of 255 0 0 in RGB ?
But how about say..Grey color, in RGB it's 127 127 127.
In ChunkyChunk format it's become 0.5 0.5 0.5 ?
Or it cannot accept value other than 1 or 0 ?

I know i can test this out, but i'm afraid i will break something,... so, it's better to ask directly to you.

Thank you once again, this is awesome !

0.5 0.5 0.5 is grey, and it is RGB. The first number is the red component etc.
Just that it goes from 0 to 1 (decimal numbers) instead of 0 - 255 (integers). Anything between 0 and 1 is ok, 0 and 1 included.
RGBA is also available if you want to specify an alpha value. so you can have transparent green if your write 0 1 0 0.25 or something.

If the format is wrong then it will just default to the player color.

That will be enough. Thanks a lot!
