[ Colour Theory ]

Colour theory is both the science and art of using colour. It explains how humans perceive colour; and the messages colours communicate artistically and emotionally.

RGB V.S CMYK

Cyan, magenta, yellow and black (CMYK) are the primary colours of printing while RGB colour is used to display on computer screen.

RGB

[ Additive colour mixing model ]

- Colour is created by mixing red, green and blue light sources of various intensities.

- TVs, screens and projectors use red, green and blue (RGB) as their primary colours.

CMYK

[ Subtractive colour mixing model ]

- created by the subtraction of light

- The CMYK colour system is the colour system used for printing

Hue, Shade, Tint and Tone

Hue

the most basic of colour terms and denotes an object’s colour

Shade

a hue to which black has been added [ red + black = burgundy ]

Tint 

a hue to which white has been added [ red + white = pink ]

Tone 

a colour to which black and white (or grey) have been added

Colour Harmony

The arrangement of the colours in design in the most attractive and effective way for users’ perception

Monochromatic

Monochromatic is hard to make a mistake and create the distasteful colour scheme

                                       figure 1.4 & 1.5 - monochromatic                                          

Analogous

- 3 colours located right next to each other on the colour wheel

- usually one of the three colours predominates

   figure 1.6 - analogous

                

Complementary

- opposites on the colour wheel

- opposite to analogous and monochromatic since it aims to produce high contrast

- make imagery pop, but overusing them can get tiresome

   figure 1.7 - complimentary

Split - Complementary

- involves the use of three colours

- start with one colour, find its complement and then use the two colours on either side of it

Triadic

- evenly spaced around the colour wheel and tend to be very bright and dynamic

- Using triadic colour scheme creates visual contrast and harmony simultaneously

The Psychology of Colour

- Colours have an extraordinary ability to provoke specific emotions for each individual and to attract people’s attention and harmony simultaneously

- While perceptions of colour are somewhat subjective, some effects have universal meaning

  figure 1.8 - universal meaning of the psychology of colour

Warm V.S Cool

Warm Colours

- often evoke feelings of happiness, optimism and energy

- Yellow, red and orange can have an attention grabbing effect and signal danger or make you take action (think stop signs, hazard warnings and barrier tape)

Cool Colours

- usually calming and soothing but can also express sadness

- Purple is often used to help spark creativity as it’s a mixture of blue (calm) and red (intense)

Black

- often used sparingly, such as for text but it works quite well as a primary colour element (like for backgrounds)

- adds an air of sophistication and elegance, and also mystery, though with much bolder confidence

White

- gives off an impression of clean, virtuous, healthy

- pairs well with just about anything, making it ideal as a secondary colour
