Answer 1

Hint: Primary colours are sets of colours that may be combined to form a useful range of colours. The colours which are not formed by the mixing of colours are known as primary colours.

Complete Answer:
Light is a continuous spectrum of wavelengths which are detected by the human eye. The human eye normally contains only three types of colour receptors, known as cone cells. Each colour receptor is responding to different ranges of the colour spectrum.

The colour receptor is known as trichromats. If the three colours of light can be mixed to produce white colour is known as the primary colour and standard additive primary colours. They are red, blue and green.

Therefore the correct answer is blue, green and red.

Note: The primary colours are not a fundamental property of light but related to the physiological response of the eye to light.
