It was nice to get a name check and a generous acknowledgement as a root source on this page.
So I hate to throw some shade on such a worthy project (especially one that was kind enough to name me) but I should point out that there are a few questionable entries on this list. Missing (unless I am going blind!) is Richard Plantagenet, Duke of York, [the original Yorkist] whose colours were azure and argent (blue and white). Confusingly these were the exact reverse of the other royal colours of Henry VI and their cousin the Duke of Somerset. Colour confusions may have led to York's death at the disastrous Battle of Wakefield in 1460.
Colours were often inherited from generation to generation as my own list in Bills, Bows and Bloodshed 2.2 shows. I also reproduce the known 100 Years Wars colours in my book to further demonstrate this. There is also the suggestion that York's surviving sons Edward Earl of March, George, Duke of Clarence and Richard, Duke of Gloucester changed the inherited family colours from blue and white to blue and murrey (blood red) to symbolise the loss of Richard Duke of York and their brother Edmund at the Battle of Wakefield. Most common men were illiterate and the murrey (wine or blood red) would be a powerful visual symbol and reminder of the family sacrifice.
Which means that the entry for Edmund as 'blue and murrey' is highly unlikely – as that murrey is symbolising HIS death and that of his father. He has no need of a standard or colour change after his death.
Another questionable entry is that for Howard, Duke of Norfolk, as – discussed by me, in detail, in BBB 2.2 – there are numerous contemporary documents which described the Howard livery as BLACK. These include a gift of black cloth to the family by Edward IV and it being specified in that document as HIS livery. The Freezywater standards book has frequently been misread as it does specify in that book that his standard was red ONLY (no white) and this is further confirmed in the Osprey Men At Arms No 145 on plate G1 and in the text. Red and white was his son's colours.
Also missing from this list are bends and 'bendys'. The suspicion about mis-identification of colours at Wakefield and the surviving son's change to blue and murrey is further deepened by the use (by Edward) of coloured bends or sashes of red to be worn over the livery colours. These bends resemble school gym bands and served the same purpose. Edward was some 15 years late settling the mercer's bill for this cloth so we know he issued red bends in 146061 campaign. Around the same time, and possibly for the same purpose, Margaret of Anjou was issuing bends in her son's colours of red and black.
Did both sides fear a 'blue on blue' after Wakefield?
