Short description of error
Grease Pencil doesn't treat color like the rest of blender
Exact steps for others to reproduce the error
The attached blend file grease_pencil_color_bug.blend has a material color and a grease pencil palette with a stroke color. Both are the same color:
the grease pencil color was copied from the material color.
The bug is that grease pencil displays (both in the viewport and in the color picker) a different color value from what the material does.
In the file, the stroke's blue component is 0.094, whilst it is 0.009 for the material. The same issue occurs when copying the freestyle stroke color to grease pencil stroke color, which suggests the bug is in how grease pencil represents color.
