'''Green''' is a colour color made by combining [[yellow]] and [[blue]]. Green is the colour color of many plants and living things.
In the poem "Nothing Gold Can Stay", [[Robert Frost]] wrote:
Green is also a term used to refer to environmentally friendly products. So ''green'' energy could be [[hydroelectric]] for instance, instead of [[fossil fuels]].
The colour color green corresponds to [[wavelength|wavelengths]] of 520 nanometers to 565 nanometers in the [[electromagnetic spectrum]].<ref>http://hyperphysics.phy-astr.gsu.edu/hbase/vision/specol.html#c1</ref>
