Thanks Dick. I concur there is no lighter area in the photo you have posted named KGV P3. Do you have a date for this photo by any chance? The camouflage scheme was modified over time, so I suppose the key point is to compare like with like time wise?
It actually raises more questions than it answers because to me it looks like there are three colours on the aft funnel. Also the change to the lighter colour at the funnel top is well above the level of the searchlight platforms. It is level with the searchlight platform in the latest suggested colour scheme drawing for 1943. See annotations below:

Assuming the Imperial War Museum has the correct date listed on the photo, then the photo I posted earlier is from October 1942. I post it again here below for discussion, enlarged as much as I can using the IWM online tool. To further show what I meant as regards the pattern on the forward face of the aft superstructure:

As regards the lighter vertical section of the aft HACS Director support structure could it simply be a reflection off the edge of the structure? The structure does not seem to be perfectly triangular in plan, seems to have a very short length of straight edge parallel to the ship's side?
Again, we know for a fact that H.M.S. Howe had her camouflage scheme modified. As did KGV herself. So there is clear precedent and evidence for modifications to the scheme. Just seems to be a question of figuring out what was modified and when? And what colours?
