Colour Theory: Colour and contrast

Subjective Colour

Chromatic Value:

 - hue, tone and saturation is what is spoken about when we discuss colour, as these make up colour. Give each colour a chromatic colour, 

• complementary colours are those opposite colours on the colour wheel this is because the complementary is made by combination of two primaries. 
• neutrals created my mixing more colours together to reduce the colour values, mixture of primaries and secondaries with moe white added to reduce there values. Still seeing red green and blue.
• Everything we see has a colour value but depends on its hue, tone and saturation which can be altered to create different colours. 
• whenever looking at anything we still see full spectrum colour as if not aware of this problems begin. Colour will effect legibility within text if not carefully considered.

Series of Contrasts:

Contrast in;

• tone:

 This can be seen by looking at black and white, series of colour contrast that allow different colours to be visible through the contrast which allow for differentiation. The simplest form of this Rods working out black, white and greys. Contrast allows for things to be seen easily as black and white are quite high contrast. However using tones/shades of the same colour make it moe difficult to see due to little contrast. 

• hue:

juxtapose differs colours and identifies the greatest contrast. The contrast in hue allows for colour to be recognised based on the wavelengths. Isolated colour of white and black background shows the colour has a tonal value due to contrast in hue. Contrast of hue looks purely at the tonal value and the colours they create, closer in hue the colours, lower the contrast.  Colour and tone confuse the eye as unsure of what its supposed to be reading as the chromatic values are closer together.

.

• saturation

Juxtaposition of light and dark values and their relevant saturations. variations in saturation effect her the eye sees the shades as colours appear lighter and darker when variation in saturation are used. Tone, hue an saturation work together within the contrast of saturation to see how pure a colour is. 

• extension 

Formed by assigning proportional field sizes in relation to he visual weight of a colour also known as contrast of proportion. Relates to he differs amount of colour available within a colour field, different ares are used to create a colour/optical balance. Used to focus attention towards a specific area based on the size of colour fields being used in order to offset another colour. When colours start to break apart, more smaller areas, confuses the eye as has to work out what its looking at, as the eye is taking in to much information. 

• temperature 

Relates to the juxtaposition hues that can be considered warm or cool. Oranges and reds are associated with warmth whereas blues are seen as cold colours. The use of different tones of red can create a cooler red based on the contrasts created when they are overlapped or placed next to each other. borders between colour create gradients as colours next to each other warm others up causing the border to seem cooler. however this is a optical illusion created by the eye which is removed through the use of black borders. 

• complementary contracts

using complementaries next to each other create uncomfortable colours to look which can be seen by placing red and green next to each other due to high contrast created. Black and white are effective complementary contrasts which are comfortable.

• Simultaneous:

Colours react and respond to each other based not their primaries and complementaries based on all contrasts working together. 

Colours begin to change based on the contrasts working together.If you intrude colours with neutrals the colour will try to impose other colour into the neutral. 

• After Image:

How are eye see and perceive colour as well as the memory of the eye. When you look at something that is bright and look away you can still see aspects of the image. Eye remembers colour that it’s seeing, as information seen by rods and tons burns information into the retina. Eye seeing saturated light to the eye flips the colour in order to balance the colour.
