For me, black or red on the number 1 car doesn't really make a difference. I just look to see if its Yellow or not.
The yellow really stands out.
Just out of interest, why did they stop using the Red T-Cam anyway ? Plus as we can all see in this photo, drivers helmets are so hidden, and this is a view that you can see the most! The side and rear you can't hardly see anything of the helmets!
