Ahem. The red coat was officially adopted as the uniform color for the army by the English Parliament in the New Model Army Ordinance of 1645: it was the official coat color throughout Cromwell's tenure as commander of the New Model Army in the Civil War and as Lord Protector afterwards. The red coat was worn by most British infantry officially until 1901, when it was replaced by khaki for field uniforms. It was last worn into battle in 1885 (so, 6 years after the Battle of Roarke's Drift of the Zulu movie) but was issued as a dress uniform for most regimental bands and ceremonial officer's dress uniforms - and of course, to this day it is worn by the Guards regiments for ceremonies.
So it was, in fact, the official British Army uniform throughout Victoria's reign, although the uniforms shown on the unit graphics are pre-Victorian, mostly from the 18th century and Napoleonic Wars before 1816.
And for the Civ VII speculation, just a note:
ALL regular Civ games have been originally released in September or October since Sid Meier's original Civilization in 1991, except Civ II, which came out in February 1996. Therefore, I suspect Ed's comment simply means that after March 2023 everybody at Firaxis can be put to work on Civ VII, but the earliest I would expect release would be October 2023. Waiting until September/October 2024 would almost require that they put out something Non-Civ in between to avoid an eighteen-month drought of no major releases from Firaxis, which is over a fiscal year with no new revenue stream and a hard sell to investors.
They could try updating BE, but frankly, I think that is like whipping a dead horse - it still ain't going to move no matter how big a whip you use.
