Short description of error

Grease pencil does not really handle unified paint settings well. As a consequence it can happen that colors are not updating in the UI when picked from a palette

Exact steps for others to reproduce the error
from the default startup scene:

C.scene.tool_settings.unified_paint_settings.use_unified_color = True
add a greasepencil stroke
enter draw mode
switch to Color Attribute paint mode
try changing a color by clicking on a color in the palette, nothing happens

When unified paint settings are used, the values are not ending up on the brush, but on the unified paint settings, grease pencil is ignoring this throughout it seems

Original report

Short description of error
[Please fill out a short description of the error here]

I created a grease pencil scene.
On this scene, I draw in color attribut.
If I choose a color in the palette, the active color attribut is not updating.

I upload a gif with the error.
This occirs also in the last 4.0.2.
This doesn't happend from a blank scene of course.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

As I couldn't really reproduce the error from scratch, it seems my scene is corrupted somehow, I share my scene. I open this scene in many other blender release, including the last 4.0.2 and the result is the same.

I dont really understand what I did wrong. I used some addons, but nothing really special.

OK, took me a while to figure this one out:

The scene SH_002 scene.tool_settings.unified_paint_settings.use_unified_color is turned ON.

If you set this to False, the color is then propagated to the Brush (and it seems GreasePencil assumes just working with brushes and is not considering UnifiedPaintSettings properly).
