Probably sponging. Using less the further back you go.

This I did with Shellac using Beau as a base and sponging Black Pool on to the tip. Use the straight edge of a fresh piece of sponge you can then use tiny taps back and forth whilst simultaneously moving side to side to get the blend... Then cure, then I often sponge the tip with Black Pool again just to darken x

I think the quickest and easiest way would be to use a black additive powder. You won't need to cure extra layers and will get a good fade
