KSLI uniforms - by: Stephen2565

I have two photos of my GF taken in India after he left SA with 2KSLI in 1903. One of them is in a khaki uniform that I am told was his SA uniform. The second appears to be a dress tunic. My questions are:
Would the khaki uniform have been used in both SA and India?
Was the tunic red?
If anyone has colored drawings of the two uniforms or links to such they would much appreciated
