A colour wheel is a great tool for home decorating and all colour schemes in design are based on this wheel. Sir Isaac Newton developed the first circular diagram of colours in 1666. Since then, scientists and artists have studied and designed a lot of variations of this concept.
There are three primary colours: red, blue, and yellow. These colours cannot be created from the other colours on the wheel, but all the other colours are combinations of these three. They seldom exist in their full intensity. 1) ________ For example, navy is a darker version of blue and cranberry is a darker version of red.
Secondary colours are formed by mixing two primary colours. They are green, orange and purple. 2)_____________
Besides primary and secondary colours, specialists in interior design also use some colour combinations called "designer" colours. Tertiary colours are made by mixing primary colours with the secondary colour next to them, for example, yellow and orange, red and orange, red and purple, blue and purple, blue and green or yellow and green.
Analîgous colours are any three colors which are side by side on a 12 part colour wheel, such as yellow-green, yellow, and yellow-orange. These colours have a common base colour, for instance, blue, blue-violet, and violet.
Complementary colours are any two colours which are directly opposite each other. 3) ____________
Triad colour schemes are formed by three equally spaced colours on the wheel. An example is red, blue and green - spaced with two colours between.
Split complementary colour schemes are made from finding complements - like yellow and purple - then choosing the colours on either side of the complement - like blue-violet and red-violet.
The following properties of colours make a great difference in any colour scheme. Value is the lightness or darkness of a colour. Intensity or saturation is the brightness of a colour. For example, a full intensity red is hard to live with.
Colour temperature is the warmth or coolness of the colour. 4) ________
