Infantry packs contain both Kings and Regimental colors for each battalion.
1768 Royal Warrant: The second color to be the color of the facing of the regiment, with the union in the upper canton; except those regiments which are faced with red, white or black. The second color of regiments faced red or white is to be the red cross of
St. George in a white field, and the union in the upper canton. The second color of those which are faced in black, is to be
St George cross throughout; union in the upper canton; the three other cantons black.
This was never put into effect, the Regimental color of regiments with black facings being as those with red and white facings.
According to inspection returns for the 50th Foot, that regiment received issues of colors in 1763, 1778 and 1786; none of the inspection returns records the colors
being white, or in any way non-regulation. The 58th Foot are recorded as receiving colors in 1763, again no mention of white.
The 64th received colors in 1766, again no reference to them being non-regulation.
There are no surviving records regarding the issue of colors to the 70th and 89th Foot between 1768 and 1796.
However, from the Regimental historian of the 50th Foot: "We've got the 1768 one hanging on the wall in the gallery - white St. George"
64th Foot certainly had a white color, as it survives in the Staffs museum.
