Render Emblematic Quarter (EQ) multicolored instead of white on map

Turning on a 'quarter filter' reveals a layer of colored hexagonal frames representing districts on the map. Makers quarter is framed with brown color, research with blue, ...etc. Color indicates district’s function. On the other side, EQs are all shown in white despite sometimes having one, two or even three functions. Multicolored hex frames for EQs would be quite helpful.
