@Augustus: That was the new plan that I came up with for squad marking as well.
Also, though I like the brighter yellow, the project had been dragging on too long... I am going to switch over to using Averland Sunset. Darker yellow with almost a tan hue, but it paints much faster and the GW Air paints have worked really well for me. Don't like the color as much but it is really speeding up the work.
