As a result, purple and magenta are known as "nonspectral" colors, because they don't really exist as actual electromagnetic ...

To understand where black falls on the color spectrum, first consider what light actually is. Light is radiation visible to ...

As evidenced through extensive experiments, the resulting system can distinguish between colors with a resolution of 10 nanometers across the visible spectrum―a level of discrimination ...

The rainbow may be due for an update. A new, high-tech method for displaying color has allowed five test subjects to see a shade beyond the standard human range.The research, published April 18 in ...

The human eye does not actually see purple, as purple is not a color on the visual spectrum. Purple is a combination of wavelengths from opposite extremes of the spectrum, which technically deosn ...

Every second, machines like drones, smartphones, and self-driving cars capture floods of visual data. But turning this data ...

As evidenced through extensive experiments, the resulting system can distinguish between colors with a resolution of 10 nanometers across the visible spectrum-a level of discrimination approaching ...

At least, when it comes to one color people think is on the spectrum. Popular Mechanics reports that purple is a “pigment of your imagination”: The human eye doesn’t actually see purple.

Incoming information from the retina is channeled into two pathways in the brain's visual system: one that's responsible for ...

Now, researchers from Japan have developed a self-powered artificial synapse that distinguishes colors with high resolution across the visible spectrum, approaching human eye capabilities.
