This is the home page to a series of articles which look at colour. Specifically they look at the RGB colour creation system used in modern visual display systems in computer monitors and in television sets. These pages describe how subtle changes in the intensities and proportions of just three different wavelengths of light give us the myriad of different shades and tones of colour which make up the world of colour today.

In this post, we explore connections between the spectrum of visible light and the use of colours from the light spectrum to represent chakras, theorized to be the energy centres of our electromagn…

Researchers have created the first "metalens" that can focus the entire visible spectrum of light onto a single point in high resolution. The breakthrough

Better understanding the characteristics and effects of visible light

Albert Einstein won his Nobel Prize in Physics in 1921 "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect" [ nobelprize.org ]. The photoelectric effect, in part, describes the energetic response from photons and electrons reg

Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength.

Isaac Newton is credited with being the first to show that white light is made up of all of the colors of the visible spectrum. He also showed that this light could be split into its different colors by a process called refraction. To...
