If by reflectivity you mean diffuse reflectivity, there's no such thing as
dark color with high reflectivity, or the opposite. The percentage of
photons diffusely reflected *is* the value of the diffuse texture.
But it seems you want diffuse and specularity together, or a BRDF. I don't
know how much information you have on the model for that.
