Staining Spanish Cedar without tainting cigars

I've noticed there's lots of lovely humi's on the market with glass fronts/ tops/ sides and Spanish cedar is quite pale and contrasting to some of the darker "outer" colours of the humi's. What I was wondering is if there's a safe way of staining/ colouring the Spanish cedar without it having a tainting (transfer of taste/ smell) effect on the cigars? Is there a way to make it a richer, darker colour safely? I thought of the wax based "rub on" stains available nowadays I've seen on DIY shows on TV.

Check this humi out and imagine it had darker coloured shelves and dividers (matching the outer colour) to see through the glass windows..surely it'd look better! Well I think it would.
