I just used a macassar ebony piece for a fretboard and it looks beautiful with it's stipes. It's on a figured black walnut gutar with a very white spruce top and it's beautiful. I made the bridge out of the same stuff.
But if you want uniform then dying is your only option. I don't think all the lemon oil in the world would blend those stripes in.
I know you didn't want opinions but that's all this discussion can be - I think you should make the wood into what you want it to be....but for me, I'd leave it just like it is because that's what it is!!
