The rule of “warm to cool” (ie warmer colours closer to the light source, cooler colours as you moved further away from the light source) is a nice place to start looking. When you start looking closely at even very gloomy skies, you’ll start to see the influence of quite unexpected colour. Scroll down to the end of this page for another example of this. It can make a sensational backdrop that will send your painting in a direction you may not have considered. This can often give you an incredibly compelling stormy sky that you never would’ve achieved if you had “tried” to paint it. This process works fantastically if you’re painting a storm using those lovely muted greys, throwing the paint on, throwing some water at it, and letting it do it’s thing. Sometimes when I’m stuck, I’ll throw some paint at a canvas, swirl it around and see if a painting appears in the mess that’s left. We'll do an exercise using this example a little later. A few small changes, and an entirely different story is told. Newsweek has reached out to Theresa Birgin Lucas for comment.Another contrasting example that springs to mind is the same sky, the same trees, but an oily sea, with an almost mirror like reflection, and some glazes to subdue the distance, and the scene is transformed to the calm before the storm. Not impossible, but clouds are typically overexposed if you also have ground in the image, so are usually very white, unless you are trying to do something to increase the contrast. "One thing we would say, from having taken many, many photos of clouds, is that producing that very dark blue is pretty difficult. Asperitas clouds often have this strange kind of lighting, so that would be a good candidate," they said in a joint-statement. We can't picture the 3D structure in our heads though, so we are not sure we can make a proper judgment on it. "We could imagine that if the lighting conditions were just right and the photo was cropped just right, maybe you could get something like this.

"I am also not sure why a cloud should be slanted towards us-it almost looks like a wall cloud but why is the upper part so far in the background?" "First there seems to be a light source on the lower left and upper right-maybe now we have two suns? Second, it looks like the lower clouds are moving in from the left, while the upper cloud is thicker on the right, which might suggest that it moves in from the right. "The picture looks fake to me," Katja Friedrich, an atmospheric and oceanic sciences professor at the University of Colorado, told Newsweek.

Atmospheric scientists are unsure what type of cloud this is, or even if the picture is real, but have suggested it may be an asperitas cloud.
