Hi TMP,
From what I have seen the Redwood Red is a darker red to the Rooster Red.
Its a bit like theres red and there's red type of thing and they will look different.
Heres an idea....
....if you like the Redwood Red, go with it for the Steering Wheel, Gear knob, Handbrake etc, and keep the colourline carbon black/piano black. To umpth up the colours in the car you could choose a black and white checkered flag interior trim surface.
I have gone for Rooster Red colourline, which is also going to be on the partial leather seats complimented with the silver checkered (standard on a S) for the trim surfaces, etc. The car is going to be Chilli Red so thought it would look really good with it.
I spent agggges, thinking about it when I was choosing!
Best of luck x
