Camouflage works by breaking up the outline of a familiar object so
that the eye/brain does not recognise it, or alternatively confuses
the eye/brain.
British soldiers in your war of independence wore red coats,
because red made it difficult for the enemy to count the number of
soldiers, to camouflage the size of their force . Ships in WW1 were
painted in garish zig-zag patterns which broke up the outline so
they were less likely to be recognised as ships and made range
estimation difficult. It is not as simple as it seems.
Sticking it to your rudder is a bad idea, as has been pointed out
earlier. Altering the mass balance of a control surface, even by a
small amount, without comprehensive testing, is unlikely to end
well.
