Leather finishing of steering wheel

Hello, get my first new used moose next week. I want to work up the leather from the steering wheel and gear knob. This looks really bad. As if the previous owner wore 5 rings on each hand. Now I have found a great guide. here I would like to get a matching color at the leather center. Does anyone know the color of the gray?! Is this the grey or something else? What did you use? Tips, recommendations? Greeting Flatattack
