Most visiable color to cover plane
This question prompted me to dig out some papers that haven’t seen daylight in loooooong time. A modeling buddy had given me a copy of an article titled “Model Aircraft Visibility”.
Don’t know who wrote it or where it originally appeared but it has some good info about contrasting colors and such.
Here is a partial breakdown of the most visible colors, in order.
Luminous Orange
White
Light Yellow
Light Orange
At the bottom of the list were:
Dark Red
Dark Blue
Black
Dark Green
The article mentions that choosing two colors, one from each end of the chart, will give best contrast under widest possible background variations.
hope this helps.
