Relevance of Colour, Part 2

In the physical plane colour is the result of light hitting an object. the colour we see is the frequency of light that is reflected off an object as light strikes it.
Colours that we are able to see form the visible spectrum.
The easiest way to become aware of the full spectrum in pure coloured light is to take an old cd (aol cds work well) and hold it in light while watching the play of rainbow colour across it,
rainbows are of course a full spectrum and have the range of secondary and tertiary colours as well as the primary colours.

Colours react with each other either by harmonizing or contrasting with each other.

The colour wheel is a valuable tool for understanding colour. A colour wheel is an image of the spectrum bent into a circle.

The colours adjacent to each other on the colour wheel form a related harmonious sequence.

When you are mixing colours of paint or pigments, The Primary colours are Red, Yellow and Blue.
Red and yellow make orange as seen on the colour wheel. When you are working with light or modern Printer's inks the Primary colours are magenta, cyan and blue.

Your computer screen is coloured by light rather than with pigment and the green (as a visible primary) may be a much lighter yellow green than the emerald or grass green hue often used as the secondary colour in pigment-based colour charts.

Primary means that in theory you can mix all other colours from them though it is not as simple as it sounds because pure red, blue, and yellow do not exist in pigments. You cannot mix the primary colours from any other colours. orange, green and violet are secondary colours and are made by mixing equal parts of two primary colours. yellow and blue make green, blue and red make violet, red and yellow make orange.

The tertiary colours are mixed from equal parts of a primary and the secondary colour next to it on the colour wheel. yellow- green, blue- green, blue- violet, red- violet , red- orange, yellow -orange, are the tertiary colours.

White things reflect all frequencies of light, black things absorb all frequencies of light.

Until next time may your day be colourful
