Are you telling me you've never seen clouds this colour in real life? You
definitely need to get out more... or just be more observant.
Never seen a Turner painting, either?

I'd guess it is all a trick of the light. I've seen skies where there are
multilayers of clouds, varying from white to blue to grey. If you live in a big
city, you're probably be familiar with that haze which is sometimes brown...

Tell you what. I once did a Google image search for "altocumulus" and got an
interestingly varied collection of results. All kinds of colours. Wierdest has
to be "altocumulus mammatus". There was one particular eerie Hollywood special
effect which I always thought was way OTT but this type of cloud really does
look like that. It's associated with storms and in more recent years, I've seen
it from my house, just before a big thunderstorm rolled in off the sea.
