I went with white as I wanted as much reflected light under the car as possible. If it becomes a hassle, then it's easy to replace with a different color.
White is supposedly an easier colour to keep clean. If you think of car colours, black always shows up the dirt, where white not as noticable. I am going through the same dilemma at the moment of what colours and pattern to lay. All help is welcome. BTW the colour combo works beautifully with the colour of the Cobra - well done
The garage looks great, as does the matching cobra. I have a gray and silver cobra and plan to use black and alloy or graphite next month. Still trying to decide the color combination.
