Colours of Colonel Du Cambon's Huguenot Regiment of Foot 1690 as reconstructed by Michael McNally

I recently acquired Michael McNally's Helion volume St Ruth's Fatal Gamble on the 1691 Aughrim campaign and the end of the war in Ireland. It has a depiction of the colours of Cambon's Huguenot infantry regiment as carried at the Boyne in 1690. The book says (p.282) "the reconstruction has been based on the relevant section of Jan Wyck's painting of the Battle of the Boyne, in which the crossing of the third battalion of the Huguenot Brigade can be clearly made out, together with the unit's white colonel's colour and a blue company colour which has golden decoration in the canton on the upper hoist side". I have examined a reasonably high resolution digital version of the Battle of the Boyne painting and cannot find the regiment as described! But apparently there are many versions of that painting and perhaps I have not found the one that shows the Huguenot regiment as McNally describes it...

Here is my version of the flag set as reconstructed in the McNally book:

  

Interestingly, McNally refers to the three Huguenot infantry regiments as the Red, White and Blue regiments of foot (frustratingly with no mention of source for that statement). On the basis that, in the English Civil War, units so called had flags of the corresponding colours, and that it rarely referred to uniform colours, does that mean that it is possible that the three Huguenot infantry regiments had red, white and blue flags? If Cambon's flags were blue, which of La Meloniere's and Belcastel's had white or red?

Update: I have found an image of the Boyne painting that may show what McNally interprets as the Cambon regiment with the flags shown; here is a zoomed in snapshot. I can just about see the blue canton with golden decoration on the upper hoist side, I think!
