I have been looking at pictures of ZK-OKQ in its All Blacks colour scheme which I think is really nice and it got me thinking why there haven't been more airlines with black colour schemes as they can be quite nice.

Is there a performance related issue with black paint - i.e. heat retention that is solved using lighter coloured paints etc etc? Or is it simply a marketing related choice?

New Zealand; black coloured coloured plane - of course it's marketing.

Blacck paint = More Weight, More heat, difficult to detect surface defects.


Think of the brighter side!

Not really no.
The black paint, is applied properly will weigh about the same as a normal white base coat.
Any difference in weight is so slight, it's not worth worrying about.

If you paint it white, then black, then the other colours, yes that will be heavier.
But if you subsitute the white base layer for black, there's no issue.

Black might show up dinks and dents more readily, but this is not much of a concern.

Modern AC systems on planes easily handle any excess heat a paint job might cause.
But with todays paint technologies, I very much down a black plane will be any hotter than a white one sitting beside it, when under ground or APU power.

I does add up to a substantial weight if you extrapolate the cost over an entire fleet of aircraft and the distance it is flown. Also, the cost of cooling an aircraft for the comfort of the passengers and crew could add up over time. Yes, maybe one time would not be very expensive but in the long run, over a fleet of aircraft the colour black would add up to a considerable amount of money.

The problem is not how hot the inside of the aircraft becomes. Rather, it's how hot the surface skin of the aircraft becomes that's an issue. In th summer, black paint, at an ambient tempurature of 100F, has a surface tempurature of over 200F! Without the proper protection, anyone who touches the plane can easily burn themselves.

This article talks about gliders, but it's still relevant:
