2 tone color fade

[Philw]

is there a way to do this type of color fade in VRay for sketchUp?
I have 2 vray VSF Car colors I want to use, but I have not found a way to mix the 2 to get this type of fade between the 2 to get this type of result.

Don't you need to create a single texture that has the colors and the blend?

Thought about that but it would just be colors.
It would not have the "Flake specular" car finish I am looking for. I know in Max I can mix 2 maps and blend the transition between the 2. I have the car finish maps for VRay that some one set up and I am wondering if there is a feature like this in Vray for Sketchup where i can mix maps, so far I have not found this feature in this program.

Ok this is what I am looking to do and what got me on this quest to find the solution in VRay for Sketchup.

I have other personal project I am working on that this would be helpful on.

Given the RGB of the two colors, you can generate a color gradient using the following code

mod = Sketchup.active_model
sel = mod.selection
clr1 = Sketchup;;Color.new [162,63,42]#change rgb to match first color
clr2 = Sketchup;;Color.new [198,184,51]#change rgb to match second color
faces=sel.grep(Sketchup;;Face).sort{|a,b|a.bounds.center.x<=>b.bounds.center.x}
faces.each_with_index{|f,i|
  clr3 = clr1.blend clr2,1.0-i.to_f/(faces.length-1).to_f
  f.back_material=f.material=clr3
}
