FIELD OF INVENTION:
This mention relates to a device for choosing different colour combinations. More particularly it relates to a device for choosing colour combinations such as harmony, contrast and complementary colour combinations.
BACKGROUND OF INVENTION:
Sir Isaac Newton created the first colour wheel hundreds of years ago by splitting white sunlight into red, orange, yellow, green, cyan, and blue, men connected the ends of the colour spectrum together to demonstrate natural colour progression.
A century later Johann Wolfgang Goethe studied the psychological effect of colours and discovered that some colours gave a feeling of warmth and others a feeling of coolness. Using these results he created a colour wheel based on the psychological effect of each colour with one side being the plus side of red, orange and yellow and the other side being the minus side of green, purple and blue.
Colour theory was developed further by Johannes latten, a Swiss color and art theorist at the Bauhaus. He modified the colour wheel using red, yellow, and blue as the primary colours and modifying these to twelve hues including secondary and tertiary colours.
Colour wheel consists of three primary colours are red, yellow and blue. The colours are called primary because they cannot be mixed from other colours. When formed into a circle and each of the three primary colours is mixed with it adjacent colour, secondary colours are created. For example, combining red and yellow results in orange, yellow and brae results in green, and blue and red results in purple. A third tier of colours is created by mixing one primary with its adjacent secondary colour resulting in yellow/green, blue / purple, red/purple, red/orange and yellow/orange. Subsequent tiers of colours can be created by continuing to mix adjacent colours.

The sequence of colours on a colour wheel isn’t happenstance. It is based on the order in which colour appears in the spectrum of light from the shortest wavelength to the longest Red, orange, yellow, green, blue and purple is the sequence seen in a rainbow. When these colours, are arranged into a circle, a colour wheel » formed, Intermediary colours are created by combining adjacent colours as described above. Various colour value (the lightness or darkness of the colour) are created by adding varying amounts of white (creating a tint of the colour or Mack (creating a shade of the colour ). Fashionable colours, colours which are in vogue at a given time, are created by adding grey to the colour or hue.
Colours affect human beings emotionally, physically and mentally. Understanding the effects of various colours on the mind and body is an important factor for the purpose of choosing the right and perfect colour and how colour can work for people in their homes and surroundings. This requires special skill. The effects of colour can be briefly described as follows:
a) Red represents the colour of light, energy, vitality and power.
b) Orange colour represent the emotional stimulants.
c) Yellow is the colour of intellect giving clarity of thought, awareness and curiosity.
d) Green colour signifies healing giving feeling of renewal, peace and harmony.
e) Blue represents the colour of truth, serenity and harmony.
f) Purple colour purifies thoughts and feelings connecting to spiritual self-bringing guidance, wisdom and strength.
As colour imparts human mind, nowadays people are giving more attention towards the colour combination in their house, shops etc. As the people are not aware of colour combination schemes & its related aspect, most of them approach the interior designer. But is very expensive.

DETAILED DESCRIPTION OF THE INVENTION
The above, and the other objects, features & advantages of invention will become apparent from following description read in conjunction with die accompanying drawings.
Before discussing die invention in detail first we will see die definition of die terms being used in die description.
1. Contrast Colour Scheme:
This means die combination of three colours which are equidistance on die colour wheel from each ether. e.g. Red+yellow+Wue

7
Red-purple+yellow-orange + blue-green
2. Complementary Colour sheme:
Working with opposites on the colour wheel is called a complementary colour scheme.
eg. Red & green are complementary colours to each other.
3. Split complementary colour scheme:
Split complementary schemes are where instead of using the direct opposite colour on the colour wheel, one can use die colours either side of die complementary.
eg. If blue is main colour - its opposite is orange, but the split complementary colours are yellow-orange and red-orange.
4. Harmony colour scheme:
Harmony colours lie next to the main colour to form an analogous scheme. They harmonise with the main colour and can be used on any surface in any form.
eg. If yellow is the main colour then yellow green and yellow orange are the harmony colours.
Now we will discuss the figures in details. Referring to figure 2, colour scheme of the outer disc (A) is shown. It consists of 12 sections of the different colours based on their appearance in the spectrum of light form the shortest wavelength to the longest, ft consists of twelve equispaced, equisized sectors, each sector being of different colour following a scheme, wherein
1th sector- red colour- Primary Colour 5th sector- yellow colour- Primary Colour 9th sector- blue colour- Primary Colour

8
3rd sector - Red+Yellow- Orange - Secondary Colours
7th sector- Yellow+Blue=Green-Secondary Colour
11th sector- Blue+Red =Purple-Secondary Colour
2nd sector- red + orange "red orange 4th sector- yeHow+orange=yellow orange
4th sector- yellow+green = yellowgreen
8thsector- blue + green = blue green
10thsector- blue + purple=blue purple
12thsector- red + purple=red purple
