colors in blender vs indigo

Hi all

What are the "conversion rule"on colors from blender to indigo? Indigo sets the color darker than piked color in blender. Example hex #c0743e turns into #862c0c.
I get that it has to do with compensating for to bright colors/energy in scenes, but difficult when you're trying to color match ncs or ral color palettes for design.

OK- If anyone else can use this.
I made a scene and noted the V value (HSV) from 0-1. This is what I get:

doesn't this have to do with Blender's color settings vs the Blendigo export gamma? the color viewing space is editable in Blender's scene tab under color management. But I have also previously edited the Blendigo file to change the the gamma of exported colors (gamma.py, I think...)

What are we talking about here? Maybe about this?
The top one is 4.2.21 and the bottom one 4.2.23
The same amount of samples :shock:

I think FakeShamus is right. Blender auto correct hex or hsv colors to sRGB colorspace - I think :) . Anyway, the render result with the darker/altered color from blender is closer to the physical ncs color sample in the final output.
