Colour Theory

Colour Theory is a set of principles used to create harmonious color combinations. Colour relationships can be visually represented with a color wheel — the color spectrum wrapped onto a circle.

Colour combination is really the most important part of colour theory and designing with colors, and also the hardest. It always comes down to your personal judgement and how you look at colors. There are some rules that can be used to make a color combination that is interesting and pleasing to the eye. One rule in these matters is to use three colours.

Too many colours will make the page feel too busy and it usually makes it harder for the viewer to find the information he or she wants. It is also more tiring to the eyes. A page with too few colors, on the other hand, risks being seen as a bit boring, and can lose attention of the audience but this need not always be the case.

Primary colour: This is the main colour of the page. It will occupy most of the area and set the tone for the design as a whole.

Secondary colour: This is the second colour on the page, and it is usually there to "back up" the primary color. It is usually a colour that is pretty close to the primary colour.

Highlight colour: This is a colour that is used to emphasize certain parts of the page. It is usually a color which constrasts more with the primary and secondary colours, and as such, it should be used with moderation. It is common to use a complimentary or split-complimentary colour for this (see below).

Colour Wheel
-------------------------------------------------------------------------------------------------------------
The colour wheel is very useful when you want to combine colors in a way that is pleasing.



-------------------------------------------------------------------------------------------------------------
Analog Colours
-------------------------------------------------------------------------------------------------------------
The analog colours have colours that are adjacent to each other on the colour wheel. One colour is used as a dominant colour while others are used to enrich the scheme.


-------------------------------------------------------------------------------------------------------------
Complementary Colours
-------------------------------------------------------------------------------------------------------------
The complementary colours consists of two colours that are opposite each other on the colour wheel. This scheme looks best when you place a warm colour against a cool colour, for example, red versus green-blue. This scheme is intrinsically high-contrast.

-------------------------------------------------------------------------------------------------------------
Split Complementary Colours
-------------------------------------------------------------------------------------------------------------
Split complementary is a variation of the standard complementary scheme. It uses a colour and the two colours adjacent to its complementary. This provides high contrast without the strong tension of the complementary scheme.

-------------------------------------------------------------------------------------------------------------
Triad Colours
-------------------------------------------------------------------------------------------------------------
Triad colours uses three colours equally spaced around the colour wheel. This scheme is popular among artists because it offers strong visual contrast while retaining harmony and colour richness. The triadic scheme is not as contrasting as the complementary scheme, but it looks more balanced and harmonious.

Colours for my Charity website
-------------------------------------------------------------------------------------------------------------
For my charity website I am using an indigo colour with a light blue colour on a white background. From looking at colour theory and the colour wheel I have reserched into analogo colours for my designs. Their is one main blue which is indigo and a lighter blue as the secondary colours. I think blue is a colour to use the RSPCA, PDSA and blue cross website all use blue. Because i'm gonna be using a white bacground i want to fill the website pages with information and lots of colourful photographs. My navigation bar which I will be constructing will be indigo with white glowing writing to make it more interesting so it is not a boring website. From researching into other websites and looking at their colour schemes I can see they get audience and use the colours I want to use for my own charity website. My indigo colour could represent sadness of pets needing care because they have not been looked after very well or they have been treated cruely and need desperate vet care, then need to be rehomed to a better family who will take better care of the pets. The blue may make the photos stand out more from just using the one colour.
