The Sun's light is "white" - a mixture of all colors. When the Sun is high in the sky, the light looks "white" - the light isn't colored.
The Earth's atmosphere acts like a prism; the atmosphere bends, or refracts, the Sun's light. You have probably seen similar things on the edge of a crystal, when sunlight is split into a rainbow. When the Sun is on the horizon - actually, just a little BELOW the horizon - the atmosphere refracts the light like a prism, and as the sun sets, we see for a split second all the colors of the rainbow in sequence. One of those colors is green.
You can see the "green flash" if you are looking over a water horizon such as the Pacific Ocean (or, from Florida, the Gulf of Mexico) or from a ship. You can only see it if the western sky is clear, without clouds or fog.

The green flash is a rare optical phenomenon that sometimes occurs just before sunrise or just after sunset. It happens when light from the sun is refracted by the Earth's atmosphere, causing the lower edge of the sun to briefly appear green as it dips below the horizon. It is typically only visible for a few seconds.
