Darkening a maple neck?

Hey all, have a StingRay guitar, love the way it plays, don’t care for the way it looks — coral red with white pick guard & maple (non-RS) neck. I have ordered a shell pickguard which should be here this week. The neck is still too pale for my tastes, though. Is there any non-destructive way to darken it up other than to play it for a few years?

Will post before and afters if anybody’s curious. Or if anybody wants to trade for a sunburst, now’s your chance!
