Color of Oil question

I checked the level of my oil the other day (I have 510 miles on the Jeep) and it was fine but surprised how black it was. I assume this is normal to be so black in a diesel? My oil life says I have 96% left. Anyone know why this low ash oil turns black so fast? Mike

Soot from the diesel combustion process changes the oil color. So I've read anyway.

That's just Diesels. I had a Firestone tech tell me my VW TDI needed an oil change when I went in for an alignment once. I asked him how could he tell and he said it's really black. I said you know it's a TDI right, and he insisted that the oil was too black. I informed him that's the color of the new oil 30 seconds after starting it, I don't think he believed me.
