Composition of Colour Party's

[Quicksilver]

1. I have a friend who wishes to produce a British Inf. Regt. Colour Party of the Crimean War 1850s era, in 54mm size, but he is not sure of the personnel making up the group. He made a set of a colour party of the Coldstream Guards 1854 with two ensigns with colours and four colour sergeants, but he is not sure if personnel are correct.
2. He has produced a colour party, Gordon Highlanders 1815 based on information he was supplied which is composed of an officer, two ensigns with the colours, and two colour sergeants. Would this be this be correct for 1850s-1860s?

If any one can help on this matter it would very much be appreciated.
