Colour Research

Colour is a form of non verbal communication. Our preference of colours changes with our mood, experiences and our surroundings. Colours can also affect us in many ways, both mentally and physically. For example, red has been known to raise one’s blood pressure, while a forest of green soothes one’s eyes.

The primary colours are red, blue & yellow.
The secondary colours are green, orange & purple. (Combination of primary colours)

Warm and cool colors

The colour wheel or colour circle can also be divided into two portions – warm & cool colours.
Warm – red, orange, yellow (yellow being the warmest)
Cool – green, blue, purple (blue being the coolest)

The colour wheel is also the commonly used tool for colour mixing and combination of colours. Traditionally, there are a number of colour combinations that are considerably more pleasing to look at. These were obtained through the application of colour schemes – complimentary, analogous and triadic, split-complimentary, rectangle (tetradic) and square.

Complementary colour scheme:

complementarycomplementary scheme
Colours that are opposite each other in the colour wheel. For example: red and green, blue and orange, purple and yellow.
The high contrast of the opposite colours produces and very vibrant look, and could be jarring to the eyes if used in large amount and in high saturation.
Such a colour scheme can be challenging to strike a balance in colours, but is very effective in creating a focus and making one of the objects stand out from its background.

Analogous colour scheme:

analogous schemeanalogous

Colours that are next to each other in the colour wheel. For example: Red and orange and yellow, green and blue and purple.
This colour scheme is often found in nature as the colours match very well and are soothing, pleasing to the eye. The three colours support each other and create a serene, comfortable design. However, this colour scheme cannot be used to create high contrast.


Triadic colour scheme:
triadColours form a triangle in the colour wheel. For example: orange and green and purple, red and yellow and blue.
Triadic colour schemes are vibrant and create a good contrast. When carefully balanced, the colours can be harmonized successfully, producing an attention catching work that is at the same time pleasing to the eye. triadic scheme





Split-complimentary colour scheme:
A variation of the complimentary colour scheme. In addition to the base colour, it uses the two colours adjacent to the complement. split-complementary scheme
This colour scheme has the same strong visual effect as the complimentary colour scheme, but has less tension and is less jarring. Similarly, a good balance of the three colours is required for an effective composition.
Rectangle (tetradic) colour scheme:
Uses four colours that form a rectangle in the colour wheel; consists of two pairs of complimentary colours. A rich colour scheme that allows plenty of room for variation. One can play around with all four colours, warm and cool. rectangle scheme

Square colour scheme:

This colour scheme is similar to the rectangle, but with all four colours equally spread out in the colour wheel. Similarly, this allows plenty of variations and possibilities in the arrangement of warm and cool colours. The square colour scheme works best if one colour is made dominant. square scheme
