Does the rubber color affect the performance of a rubber?

The pigment mixed during the production of the surface sheet determines the color of the rubber.

The performance of Tenergy 05's sheet is different from the performance of Dignics 09C's sheet. If both are Tenergy 05, the performance of the sheets is exactly the same. And since only a tiny amount of pigment is added to the sheet, there is almost no difference in performance between the same type of rubber.
