Rarely, the green flash can resemble a green ray shooting up from the sunset or sunrise point. Green flashes occur because the Earth's atmosphere can cause the light from the Sun to separate, via wavelength varying refraction, into different colors. The green flash is a rare optical phenomenon above the horizon directly at sunrise or sunset.
The color is caused by green light from the sun that survives atmospheric refraction so that it can. The Green Flash Color Scheme has 4 colors, which are Medium Sea Green (#39C05E), Screamin' Green (#4FE64A), Kiwi (#86FF4C) and Green-Yellow (#BDFF3F). The RGB and CMYK values of the colors are in the table below along with the closest RAL and PANTONE® numbers.
The green flash has reached mythical status due to its rarity and unpredictability. Learn how and when to see this elusive optical phenomenon and what causes it. The green color is produced by atmospheric refraction of light, which causes objects near the horizon to appear slightly higher in the sky than they really are.
The green flash is a rare, brief optical event of green, yellow, and sometimes blue that colors the horizon, occurring at sunrise or sunset most often in the western U.S. Refraction and dispersion cause the green flash, and there are four different types of green flashes that can occur. The green flash is tied to pirate folklore.
The word "flash" refers to the sudden appearance and brief duration of this green color, which usually lasts only a second or two at moderate latitudes. These pages illustrate and explain green flashes, offer advice for seeing and photographing them, and provide information about other refraction phenomena, such as mirages.

What's a green flash? Green flashes are real (not illusory) phenomena seen at sunrise and sunset, when some part of the Sun suddenly changes color (at sunset, from red or orange to green or blue). The word "flash" refers to the sudden appearance and brief duration of this green color, which usually lasts only a second or two at moderate latitudes. These pages illustrate and explain green.
The green color in a green flash is caused by the scattering of light in the Earth's atmosphere. As the sun's light passes through the atmosphere, the shorter wavelengths of light, such as blue and green, are scattered more than the longer wavelengths, such as red and orange.
