Thunderhead Sunset 2
a highly idealized fantasy world
The combination of water vapor in all its forms and the sun dipping below the horizon combined to form these magical images.
Maxfield Parrish refined his art to duplicate these effects in oil.
Parrish’s art is characterized by vibrant colors; the color Parrish blue was named after him. He achieved such luminous color through glazing. This process involves applying layers of translucent paint and oil medium (glazes) over a base rendering. Parrish usually used a blue and white monochromatic underpainting.
His paintings/illustrations were unique in that they depicted a highly idealized fantasy world that was accessible to the public. Although you will rarely see a glimpse of that color in reality, he was and still is linked with a particularly bright shade of blue that coated the skies of his landscapes. And it was not an easy task for him to complete. He invented a time-consuming process that involved a cobalt blue base and white undercoating, which he then coated with a series of thin alternating coatings of oil and varnish. When exposed to ultraviolet light, the resins he employed, known as Damar, fluoresce a shade of yellow-green, giving the painted sky its distinctive turquoise tint.

Just the Facts
Cumulonimbus (from Latin cumulus ‘heaped’, and nimbus ‘rainstorm’) is a dense, towering vertical cloud, typically forming from water vapor condensing in the lower troposphere that builds upward carried by powerful buoyant air currents.
Above the lower portions of the cumulonimbus the water vapor becomes ice crystals, such as snow and graupel, the interaction of which can lead to hail and to lightning formation, respectively. When occurring as a thunderstorm these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along squall lines.
Graupel also called soft hail, hominy snow, or snow pellets, is precipitation that forms when supercooled water droplets in air are collected and freeze on falling snowflakes, forming 2–5 mm (0.08–0.20 in) balls of crisp, opaque rime.
Graupel is distinct from hail and ice pellets in both formation and appearance. However, both hail and graupel are common in thunderstorms with cumulonimbus clouds, though graupel also falls in winter storms, and at higher elevations as well.
These clouds can produce lightning and other dangerous severe weather, such as tornadoes, hazardous winds, and large hailstones. Cumulonimbus progresses from overdeveloped cumulus congestus clouds and may further develop as part of a supercell. Cumulonimbus is abbreviated Cb.
