This photo was taken in New Zealand in March 1901, when an Indian contingent was sent to Australasia for the celebration of the Commonwealth of Australia. There were 30 Indian officers from different regiments as well as 5 British officers and 65 NCOs.
Sadar Bahadur Ram Singh is wearing a blue kurta with a white collar and gold lace around the edge of the collar and down the front. The cuffs are rarely seen in photos of Indian Officers as they usually wear white gauntlets. He has two wide strips of gold lace on his pointed cuff but the cuff itself is the same blue as the rest of the garment. One would expect it to be white like the collar. The picture of Risaldar Major Man Singh shows him wearing a kurta with white cuffs but that is at an earlier date, some time in the 1880s. W Y Carman in his book on Indian Cavalry uniforms does not say what colour the cuffs are, so this photograph confirms the blue colour.
