The "two tone black and grey" (grey seats and some panels) is only available in Blue and Forest Mist Green (where it is the only choice), Silver and MSM (where you can also get all black). There is no scarlet pearl with anything but the beige interior.
Personally, I was going to get the blue but IMHO, the grey interior is too "cut up" into many different tones. One reviewer called it a "cacophony of colors". I agree so decided on the more consistent MSM with black interior. Of course it is all about what you like so there is no right or wrong but there is no scarlet pearl with anything but the beige and that looks even more cut up, color-wise, IMHO.
