A very thought provoking image appeared on Astronomy Picture Of The Day yesterday. The boys at NSF ran the sun’s light through a spectrum to see what visible light the sun produces. As you can see from the image, there are swatches of color our sun doesn’t make.

This understanding might have a practical application in the Usability space. We as humans have evolved over the years to see color. But, humans may have difficulty discerning certain colors due to their rarity in nature. This may be something to take into account when trying to decide on the use and application of certain colors in the products we create.

Food for thought at least…
