Airport; Procedure
Taxi clearance was from our gate via Kilo; Golf; to Runway 36R. I followed the big fat taxi line on Kilo anticipating to see a curved taxi lane marking towards the right to join Golf. Unfortunately; the taxi lane marking from Kilo ends at a right angle on a way smaller taxi lane marking on Golf. As it was dark; it looked like taxi lane Kilo would go straight into the grass just to the right of Taxiway F1. I did mention this to the Ground Controller to advise airport operation; but they said that nothing probably would be done about it.Repaint the taxi line markings from a right angle to a smooth circle to join taxiway Golf.
Air carrier Captain reported taxiing to TUL Runway 36R on Taxiway K in darkness and expected a curved taxi line transition to Taxiway G; but was surprised at the 90 degree dead end turn onto a narrow Taxiway G just short of the grass.
