Using an experimental technique called "Oz," researchers stimulated the human retina such that people saw a brand-new color.

In an innovative discovery that defied centuries of colour theory, scientists revealed that purple isn’t a real colour at all—but a clever illusion created by the brain. According to new research, ...

However, a new possibility has emerged: breaking those limits and unlocking a color previously unseen by human eyes. James ...

Purple is a combination of wavelengths from opposite extremes of the spectrum, which technically deosn’t make any sense, but ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

They're your eyes, and they receive signals that fall in the range of visible ... spectrum. Here's a tour that begins with radio waves and takes you through microwaves, infrared radiation, light ...

This range of colors is all that the human eye is capable of seeing—our "visible light spectrum." But what happens when waves get even longer or shorter? Looking at a chart, one quickly realizes ...

Greetings, stargazers. Spring is galaxy season for many amateur astronomers. However, when looking through an eyepiece instead of a camera for astrophotography, you might think of this as the season ...

Each colour within the visible light spectrum has its own narrow band of ... only the orange wavelengths will be observed by the human eye. An object appears to be black if it absorbs all the ...

The sensor on your digital camera picks up a lot more than just the light that’s visible to the human eye. Camera manufacturers go out of their way to reduce this to just the visible spectrum in ...
