I am trying to write a script to set Interface colours for individual scenes. When I switch scenes in the Info bar drop down menu I want to change the Info Bar background colour. This gives better feedback for scene swapping/tracking. So far I've got bpy.context.user_preferences.themes[0].info.space.header = (1,0,0)

  • I guess I need to create an open list of scenes that I can append later.

  • Then allocate the spectrum of colours to it?

  • Not sure I can create a UI to allocate colours to scenes, so I'll have to bump the values in increments instead.

But first I'm stuck on calling the colour change (I considered iterating a bunch of themes and switching them as needed). At the BA forum it was suggested that the scene change is a frame change event but I'm not sure how to separate that from any other frame changes...

Hopefully if I can set up colours for the info bar I could tie them to node scene inputs.

Cool idea, I wrote this addon for me just now and I triggered the Header draw event. You can copy it from below or from here: scene_colored_header.py

bl_info = {
           "name": "Colored Header for each scene",
           "author": "Leon95, Idea: 3pointedit",
           "version": (1, 0),
           "blender": (2, 50, 0),
           "location": "Properties > Scene Tab > Scene Panel > Display Color",
           "description": "Define a Header Color for every scene and display it in the Header",
           "category": "Scene"

import bpy

def hndl_draw(self, context):
    row = self.layout.row()
    row.prop(context.scene, "headerColor")

def header_refresh(self, context):
    #assign the property to the header theme every time it is redrawn
    bpy.context.user_preferences.themes[0].info.space.header = context.scene.headerColor[:3]

def register():
    #add a new property to the scene type
    bpy.types.Scene.headerColor = bpy.props.FloatVectorProperty(
                                     name = "Display Color",
                                     subtype = "COLOR",
                                     size = 4,
                                     min = 0.0,
                                     max = 1.0,
                                     default = (0.355,0.366,0.57,1.0))


def unregister():
    bpy.context.user_preferences.themes[0].info.space.header = (0.447,0.447,0.447)
    del bpy.types.Scene.headerColor

if __name__ == "__main__":

The coolest thing is that you can animate the header color :) –  Leon95 Aug 30 '14 at 20:57
+1 This is pretty sweet. A cool idea from op indeed, registered and currently using it. Only critique is by default the color changes are rather subtle. –  iKlsR Aug 30 '14 at 21:04
That is AWESOME, thanks sooo much! At least now I have a script to learn from, win win. –  3pointedit Aug 31 '14 at 7:18
