I'm not colour blind but can some one answer this if there are. My mate is and he can't tell the difference between red and orange.
I ask this due master warning and caution lights. When you see these lights even if you don't know the colours are they different or the same. Seams irrelevant to me. Your just looking for a light. The only thing I see that may be a problem is a glass cockpit with so much information on it. I'll be interested to here what you see and don't.
I don't think it matters a nats dick just something they found to keep them selfs employed.
Cheers
