Well, here is a rather poor photo of my Portuguese units in India circa 1750.
I will, hopefully, have better quality pictures after Christmas of all my Portuguese troops. Still trying to work the camera out : ( Again, the figures were painted by my friend Peter.
As far as I can ascertain, there were three infantry units at the time, although in the 1740s there were more infantry units stationed in Goa.
In 1744/45 the Portuguese Governor of Goa was the Marquess of Alorna. He "demanded" that the European troops be uniformed as follows:
Green cloth for coats of both regiments and red for the cuffs ...and lining of the same colour for the jackets; for another cloth dark gold colour for the cuffs and ...lining of the same colour for the jackets.
Not only was green the colour of Braganza, the Portuguese Royal House, but also of Alorna.
The two infantry regiments appear to have been named the Regt do Coronel Dom Luiz Valadares Souto-Maior and Regt do Coronel D. Luiz Pierrepont in 1735, before being renamed the Regt de Infantaria da Guarnicao de Goa and Regt de Infantaria da Cidade de Goa in 1741. It also appears that the Pierrepont regiment was the senior unit. Change in title is unclear due to the loss of records in the archieves.
In 1735, both infantry units were in white jacket, waistcoat, breeches and turnbacks. The Pierrepont Regiment had red cuffs and the Souto-Maior blue cuffs.
In 1741, the Pierrepont (now 1st Regiment) had red cuffs and waistcoat. Souto-Maior (now the 2nd Regiment) had green, blue or yellow cuffs and waistcoat. Then came the Marquess' "regulations."
By 1783 the uniforms had changed again!
Gaiters were white in summer and black or gray in winter.
Colours/ standards are conjectural and I have been unable to locate any firm information. It would be common for at least one Royal colour to be carried, although there are references to Portuguese units at home carrying multiple colours of uncertain design.

There was also the Bardez Regiment, composed of the "Portuguese of India." Essentially, these troops were of mixed race, or Christianised Indians. The Marquess required them to be uniformed in blue cloth with red turnbacks and cuffs.
There were no trained or uniformed sepoy units at this time. There were, however, "auxillary" units, equipped in native style and variously armed with matchlock, bows and other native weapons.
In regards to cavalry, there was only one unit of Portuguese cavalry in Goa at this time, the Presidential Guard. It probably never exceeded 80 troopers.
Again, the Marquess had ordered that the Guards be uniformed in red cloth. An illustration by Mr Manuel Rodrigues, who has inspected numerous contemporary records, depicts them as follows:
Artillery was also to be uniformed in blue with red cuffs and turnbacks.
I am indebted to Mr Rodrigues, Portuguese military historian for this information. Between 1990 and 2000 Mr Rodrigues inspected archieves at Cape Verde, Angola, Mozambique, Malacca, Goa, Diu, Daman, Brazil, Malta, Macau. France, England, Spain Morocco, Belgium, Italy and Germany!
