I would bet that leaving it in the Sun would bleach it rather than darken it.

I use Fiebings leather dye for dyeing bone, antler, wood, leather. Medium brown and dark brown, both the spirit based and the oil based work well. Lots of folks are using Rit dye in the liquid form and are getting great reds. Personally I'm not wild about the Tea staining by soaking in water. If you're going to dye the handles I would suggest a dry scrubbing with super fine steel wool to get any coating off the bone, it takes the colour better.
Best regards and good luck.
