I got a little too over zealous whilst cleaning and scuffed the leather on the driver door panel armrest pad.

I noticed this part is around 60 or so dollars to replace. My other option is to get some dye to repair the discolored area.
Would anyone know where I can buy some leather dye that will match the perchmant color used?
2nd choice would be to buy the new part, would I have to remove the complete door panel to access the removal of the door armrest pad? Whilst viewing images online I noticed that maybe a screw holds it down?

Thanks for your advice.
