Thanks all. The disruptive light blue snake pattern has been started on the upper wing underside to see what it looks like. Hard to get true colours in these pictures but it's light blue on silver.
Thanks Karl, that's the plan. This was a one off scheme with not a lot of information. I did mask the outer fringes of the bands and laid down some white. Blue and red to follow so I should get some pics up within a day or so.
