Which of the following are the primary colours of light?

The primary colours of light are Red, Green, and Blue (RGB). These are known as additive primary colours because they combine to create white light and a wide spectrum of other colours. This principle is fundamental to how modern technology, such as television and computer screens, displays images by mixing these three specific wavelengths in varying proportions. While the visible spectrum consists of seven colours (VIBGYOR) as seen through a prism, only red, green, and blue are considered primary in the context of light because they correspond to the three types of colour-sensing cones in the human eye. Mixing red and green light produces yellow, while red and blue produce magenta, and green and blue produce cyan. This differs from subtractive primaries used in pigments, which are typically cyan, magenta, and yellow.
