Colour is an event because it requires the participation of three components at a particular point in time to take place. In addition to the object, we require a light source and an observer<\/a>. Only with the interaction of these three things \u2014 object, light, and observer \u2014 can we have a colour event or experience.<\/p>\n\n\n\n

\u201c<\/strong>If we see someone wearing a yellow sweater illuminated by a bluish cast of light, we still \u2018see\u2019 a yellow sweater, even though we have no trouble identifying the colour in the sweater as green if it is isolated from the scene.\u201d <\/strong><\/p><\/blockquote>\n\n\n\n

We need some help from three branches of science, physics, physiology and psychology, to understand how the object, light, and observer contribute to the colour event. If you like memory aids<\/a>, you can use the acronym POLO to remind you of the three science P\u2019s and the object, light, and observer.<\/p>\n\n\n\n

Object<\/h2>\n\n\n\n

The object and light fall under the domain of physics, while we need both physiology and psychology to describe the observer\u2019s role in the colour event.<\/p>\n<\/div><\/div>\n\n\n\n

The object\u2019s role is to interact with light, and the object can either reflect light back from its surface or transmit light through itself. Reflectance<\/a> and transmission are the two potential interactions. The majority of objects are opaque, so most of the time we are dealing with the reflection of light.<\/p>\n\n\n\n

If an object is semi-opaque, and transmits a portion of light, we refer to it as translucent.<\/p>\n\n\n\n

Light<\/h2>\n\n\n\n

Visible light is a tiny sliver of the total electromagnetic spectrum. The electromagnetic spectrum contains all forms of energy, ranging from kilometre-long radio waves at one end and progressing in shortening wavelengths down through microwaves, infrared waves, ultraviolet waves<\/a>, X-rays, and finally, gamma waves with wavelengths of a subatomic dimension<\/p>\n\n\n\n
