After Rothko

Suddenly struck by how so many early-morning skies can look so much like a Mark Rothko abstract.
This morning's sky looked particularly Rothkoesque, so I framed it in portrait mode, just like the artist did almost exclusively; and clicked the shutter release to try to capture the light, like he absolutely never did.
His version of abstract expressionism was dominated by stacked rectangles of largely monochrome paint stretching across the whole width of the canvas, with the edges of one blurring into those of the next - see an example in today's Extra photo.
This is exactly what today's morning sky looked like. If you project onto it an invisible frame that excludes every other feature but the slabs of soft-edged colour rising from the sea and into the layered bands of clouds, you are left with a naturally-occurring version of a Rothko abstract - especially if you squint your eyes together a little. 
Not at all sure that such skies ever inspired Rothko, or that he ever tried to express the essence of them on a two-dimensional canvas. But the similarities with his abstracts are inescapable.
