Blender 2.8 How to make the object color in viewport look excatly as it is? So I'm making the models for a game that only uses vertex colors and no textures. 

I've noticed that any color in blender 2.8 viewport looks darker that it actually is. I use vertex painting to paint the object in 100% white, I set the "flat" shading but the object is greyish. 

Here's the screenshot with windows notepad opened above the blender:



It is obvious that the "white" torus isn't really white. 

If I use color picker to pick the color from torus it will tell exactly what my eyes see: the picked color is actually 10% darker than real white. Even worse, If I pick the color and paint with it at the same area, it will paint with that darker color. Thus the color picker become unusable in many situations.

In blender 2.79 I've set the object to "shadeless" and it pretty much solved the problem, but this option isn't really there anymore. 

Is there anything I can do to see the real colors in the viewport? 

Thanks!

Andrey.
EDIT (NEW SOLUTION): 
I was browsing the bug reports and found the answer. 
Set your Workbench viewport to Flat - Vertex Color. 
In the Overlay Settings set the Vertex Paint opacity to 0, 
this way you are going to avoid the darkening effect of your vertex colors (if not they multiply by themselves)



This is an issue I am fighting right now with.
The vertex colors viewport rendering is a mess and the solution I found is to tweak workbench to do the dirty work.

For painting if you want to have 1:1 vertex colors set your Solid view to:


Flat
Single (White)


(Object works too if your object color is set to white, you can then at least have outlines for complex scenes)

To see the whole scene with vertex colors I managed by setting Workbench's Rendered view as:


Flat
Vertex (note if you go in Vertex Coloring mode everything becomes darker)


And in color management


sRGB
Standard


So to work on on a scene with vertex colors you will have to swap between Rendered view and Solid view - It's terrible for color picking. I hope someone will fix this.
