Hi and Welcome to the Board,
Are you using worksheet cells for your Org Chart, or drawing objects?
If the org chart uses cells, then you could just apply the same CF rules to those cells.
If they are drawing objects, you'll probably need VBA. If you want some help with code for this, please...
1. Post the formulas in your CF rules
2. Use the macro recorder to record the steps of you manually changing the color of one of the drawing objects and post that recorded code.
