The painting measures 50.4 cm × 101.3 cm (19.8 in × 39.9 in). It depicts a relatively flat and featureless landscape with fields of green wheat, under a foreboding dark blue sky with a few heavy white clouds. The horizon divides the work almost into two, with shades of green and yellow below and shades of blue and white above.
The blue sky spectrum contains light at all visible wavelengths with a broad maximum around 450–485 nm, the wavelengths of the color blue. Diffuse sky radiation is solar radiation reaching the Earth 's surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere .
As a result, the cloud base can vary from a very light to very dark grey depending on the cloud's thickness and how much light is being reflected or transmitted back to the observer. Thin clouds may look white or appear to have acquired the color of their environment or background. High tropospheric and non-tropospheric clouds appear mostly ...

Type IV whirls are partial or, more rarely, complete rings of cloud with dark centres. [44] When mesospheric clouds are viewed above the atmosphere, the geometrical limitations of observing from the ground are significantly reduced. They may be observed ‘edge-on’ against the comparatively dark sky background, even in full daylight.
