Kylie Jenner: I Still Got A Hand On Tyga

Kylie Jenner is blue after her breakup with Tyga ... and the blue looks fabulous on the Ferrari he gave her before she dumped him.

Kylie zipped through L.A. Wednesday in the $260k whip Tyga gifted her on her 18th birthday. It's had a couple of paint jobs ... she got it white, but, ya know.

Later that night, she went bowling with PartyNextDoor.
