Yup! Contrast should be good. Eyes in the sky will tell.
Excellent question SpeedBoy. Just so happens I was considering that today - I don't know about actual coloured paint, given I went to the trouble of painting the cockpit and finishing it to be "visible" but I thought a little tinge would do nicely. Problem is, I've never tinted a canopy before. I know it can be done with film, usually by splitting the canopy lengthwise but I'm not crazy about that system. An actual transparent "paint-on" tint would be ideal. Maybe someone on RCU can point me in the right direction.
Have the lines got you wanting to build one? Well, just so happens they are still being produced. For $66 (quite amazing actually) + S&H you too can have one here:

Hope you decide to pick one up!
