Red is the best color for your eyes in the night time. It preserves your night vision, so you have lighting but you can still see in the dark. For the '11-'13 Fiesta the dash lighting was red and I thought that was best. I wish the dash lighting was still red. In any case, I like the ambient lighting, but keep it red so it's not messing up my night vision. They used red lights to light the pathways at a star viewing I went to at an observatory for that reason. If the orange-yellow color was more orange, I may use that if it was darker. The other colors I either don't like or are too bright.
