'''Red''' may be any of a number of similar [[color]]s at the lowest frequencies of [[light]] discernible by the [[human]] [[eye]]. Red is one of three [[primary colors]] of light, along with [[yellow]] and [[blue]]. Red light has a wavelength range of roughly 625-760 nm. Lower frequencies are called [[infrared]], or "below red", and cannot be seen by human eyes, although some infrared frequencies can be felt as heat.<ref>http://www.flickr.com/photos/lensop/sets/72157594342268252/</ref>

Red is supposedly the first color perceived by humans. Brain-injured persons suffering from temporary [[color-blindness]] start to perceive red before they are able to discern any other colors.<ref>http://www.tcrwf.org/PDF/April-2006-Newsletter.pdf</ref> [[Neolithic]] hunter peoples considered red to be the most important color endowed with life-giving powers and thus placed red [[ocher]] into graves of their deceased. This explains funds of [[skeleton]]s embedded in up to 10 kg of red powdered ocher. Neolithic cave painters ascribed [[magic]] powers to the color red. It can be stipulated that they painted [[animal]]s in red ocher or [[iron oxide]] to conjure their fertility.
