Short description of error
Grease Pencil Objects change their color in Rendered Viewport Shading Mode and on the final render according to World's Viewport Display Color, not by actual World's Surface Color.
Exact steps for others to reproduce the error
Open a new scene.
Delete the cube and light.
Add Grease Pencil Monkey object.
Switch shading mode to "Rendered".
In the "Properties" area find "World Properties" and expand "Viewport Display" settings.
Play with the color value. In the viewport you'll see Monkey changing color according to your experiments.
Black color will bring drawing to complete hopeless darkness.
Try to render the image with tinted monkey in frame. You'll see the effect takes it's place on render as well.
Now play with World's Surface color. It doesn't do anything.

@fclem Is this a know limitation?

Confirming for now, this seems wrong.

Hm, could be a limitation indeed (atm.
gpencil_light_ambient_add
is always called early on inGPENCIL_engine_init
- and with the viewport color)Added subscriber: @mendio
This is a workaround that helps to display the Gpencil object with more accurate colors in dark environments without affecting the lighting on meshes. Remember that Grease Pencil is designed for 2D art.
Maybe this workaround could be reviewed now that grease pencil objects are affected by lights and we could try to find a better solution to display the correct colors/lighting on Gpencil objects using World Color instead.
Not sure if we must keep as is and leave this when using the new Eevee mode currently in development.
exactly, this could be reviewed/updated in the new GPencil-Eevee development
Changed status from 'Needs Developer To Reproduce' to: 'Confirmed'
Just to add some precision, this is because the GPencil engine has no way to evaluate the world nodetree and the nodetree could be way more complex than just a solid color.
This is, unfortunately, going to remain a limitation. However, EEVEE's lighting of GPencil object will of course be the same as other object using the full nodetree.
