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.
