Sure, there will be a red tint no matter if you add them or average them but
in both cases the red tint is so small that it's insignificant.
Remember that the specular reflection of a light source is *many* times
brighter than the diffuse reflection of that same light source in that spot
where the highlight appears. So the contribution of the red diffuse
reflection is insignificant compared to the specular reflection - exactly
like if you had added them together.
Remember to think in terms of high dynamic range and not brightness values
clamped to a [0-1] range...
