System Information
Operating system: Windows 10
Graphics card: NVIDIA Geforce GTX 1060 3 GB

Blender Version
2.83.2

Short description of error
Sampling in Vertex mode samples the color in the view port while the sampler in Texture Paint samples the original color of the image texture.
It's more constructive to have the vertex paint mode sample the actual vertex color.

Exact steps for others to reproduce the error
With Eevee active, Paint Vertex colors on an object and press S and notice the color it samples is from the Eevee material.

Zac Nelson changed title from ~~Vertex Paint sampling inconsistent with Texture Paint sampling with Eevee~~ to Vertex Paint samples the color in eevee rather than the true value unlike in Texture Paint sampling with Eevee

Did it work in any older version ?
Is it a request for modified behaviour ?

Not sure for all of Blender's versions but in Blender 2.7x versions it worked the same. Afaik it could only be done with a workaround when in Cycles: setting the Display Method to Texture when in Vertex Paint Mode.
Similar trick works in 2.8x ff by setting the Viewport Shading to flat.
From a fellow user perspective I agree that it would be convenient to have the option though and/or that the manual could be more clear ("Press S on any part of the image to sample that color and set it as the brush color" should probably say "any part of the 3D viewport" and "viewport color" instead)

This could/should be improved, but is not considered a bug, see #63586 (Vertex paint color picker not acaccurate)

@mano-wii: you had a patch for this, right?

I made a raw patch a while ago P1032

There is a topic about color picker discussed in #71947 (Vertex Color/Attribute Edit Design)

Active vertex color picker

The painting sample_color operator should pick the color of the active vertex and assign in to the brush (or to the UnifiedPaintSettings color)instead of picking the shaded color from the viewport.

So since it would not be considered a bug atm. and is already covered by a design task, there is no need to have this open separately.

Will merge into #63586 (Vertex paint color picker not acaccurate) for now.
