System Information
Operating system: Windows 10
Graphics card: NVIDIA GTX 1050

Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-02-12 16:20, hash: 77d23b0bd7, type: Release
Worked: Never (2.80+)

Short description of error
When I bake texture to a new UV colour is changed. After bake, I use the colour picker to define the colour.
The original texture of the cube has colour #41FF6A. Cube texture with new UV has #40FE69.
I tried to bake at the same object and from one object to another - bug is here too.
!!! Importantly !!! The bug is here if the original texture does not save to a file (jpg, tif, etc). if I save the original texture to file before baking the bug is not here.

Exact steps for others to reproduce the error

Add two cube.
Cubes have to have different UV.
Set colour #41FF6A as image texture at first cube (does not save texture in a file).
Set Bake Type to Diffuse and uncheck Direct and Indirect in Bake.
Bake.
Take colour picker (I use ColorMania) and compare colours both cubes (the second cube will be #40FE69).

...
You may not action 1-5, you may open the file instead and click Bake, then go steps on.

Change UV.blend

I get a circular dependency warning. But yes, there was a change of 1 in the RBG values.

I am not able to reproduce this issue. Can you check with Blender 2.90?

Also note, that color you see on display depends on color management, so I would like to know more in detail how you actually compared colors.

I'm using the native Digital Color Meter app.

The values are of before baking. After baking, they become the 64-254-105 on both editors (so better note it already. )
