It ain’t the badge guy’s call. He can approve a badge, but the question is whether that badge can be used in place of the ATC badge on a banner. A suggestion that it can seems to be an invention of D P-H and her team.
Personally, I’d run it past the Drill WO or CRAFACWO as ceremonial people. I don’t know who owns the ACP but most of that manual has nothing to do with flags on sticks so that might not be entirely relevant.
I find it amazing that you managed to knock up a spoof squadron badge, in probably very little time, and it’s still more in line with the way they should be produced than the vast majority of those in the ATC.
I reckon that 388’s there actually is the lighter blue - it’s just been photographed in shadow.
The “other” blue tends to be far more glaringly and vomit-inducingly hideous.
