Short description of error
Using EVENT_... icons with bpy.types.UILayout.label(), it's impossible to affect them using layout.active, layout.enabled or layout.alert to draw them more muted or in red.
This seems to work for all other icons (that I have tested) however.

See:

And note how the icon is always white, and not grey muted or red like the other icons or the following text.

I've gone back to Blender 3.1 and it didn't work there either, so probably has been a thing since forever.

You can test using this little script to draw in the scene panel:

import bpy

def draw_labels(layout):
    layout.label(text="Info", icon='INFO')
    layout.label(text="Word", icon='WORLD')
    layout.label(text="Left Mouse" , icon='MOUSE_LMB')
    layout.label(text="Event E" , icon='EVENT_E')

def scene_panel(self, context):
    layout = self.layout
    
    # draw active (normal)
    column = layout.column()
    column.active = True
    draw_labels(column)
    
    layout.separator()
    
    # draw inactive (muted)
    column = layout.column()
    column.active = False
    draw_labels(column)
    
    layout.separator()

    # draw alert (red)
    column = layout.column()
    column.alert = True
    draw_labels(column)
    
    layout.separator()

bpy.types.SCENE_PT_scene.prepend(scene_panel)

Or by loading the attached .blend file, and running the script in the text editor.

Exact steps for others to reproduce the error

run the script above or the one in the attached .blend file
observe how the other icons are drawn and compare to the EVENT_E icon

Can confirm. Looks like those are "Colored icons" defined with DEF_ICON_COLOR instead of DEF_ICON_VECTOR, I guess that's why it will preserve color.

To me it would be best if it can be drawn semi-transparent or tinted red in this kind of situations.

Suggestion would be improve the GPU_SHADER_ICON into something that also accepts desaturation/tint arguments.

@ideasman42 Is this your area?
