some austrian Units/Uniforms:
Do you think these uniforms would be the right ones? Since there were some important changes in 1869 when the colour basically of the infantry uniform where changed from white to blue since white wasnt the best colour to use as one could see that in the war of 1866. Also the Feldkappe was used instead of the shako in battle.

With this colour for example:
(dont mind the ensign on the collar, this is the Oberleutnant Ballonfahrer Unit it was in the flying zepellin airship and this is actually the parade uniform.)
[edit this is the best source altough for the marching uniform:
