Contrast of tone.
Formed by the juxtaposition of light and dark values. This could be monochromatic (single colour). If you remove the chromatic value the tonal value can be defined more easily.
COLOUR EXPERIMENTS
Yellor and green have a medium contrast as they are close to each other on Ittens colour wheel.
Blue and green have a low contrast as they are close to each other on Ittens colour wheel.
Blue and orange have a stronger contrast as they are further apart on the colour wheel and blue has a darker tonal value.
Red and orange have a strong contrast of tone as red has a stronger tonal value than orange, this is clear when we look at the monochrome photo.
Blue and yellow have a stong contrast as they have as blue has a stronger tonal value than yellow.
Yellow and magenta have a strong contrast as violet has a much darker tonal value than yellow, this is apparent in the monochrome photo.
Blue and Violet form a low contrast as they have similar tonal values.
Orange and blue have a strong contrast of tone, but when we place the coloured circles on a yellow background the contrast becomes less intense.
Blue and green have a low contrast, this is not affected when placed on a coloured background.
Orange and yellow create a low contrast of tone.
Finally, I experimented with placing three colours together to see if it affected the contrast of tone. The colours red and green clearly have a similar contrast of tone as they are both quite dark. The orange contrasts these as it has a lighter tonal value.
Contrast of hue.
Formed by the juxtaposing of different hues. The greater the distance between hues on a colour wheel, the greater the contrast. Therefore, complimentary colours have the greatest contrast of hue.
COLOUR EXPERIMENTS
Green and blue have a medium contrast.
Blue and orange have a strong contrast as they are complementary colours.
Red and yellow also have a low contrast as they are both primary colours.
Red and blue also have a medium contrast.
Moreover, yellow and orange also have a medium contrast as they are next to each other on the colour wheel.
Yellow and green have a low contrast.
Blue and yellow have a low contrast.
Violet and magenta have a low contrast of hue as they are close to each other on the colour wheel, colours that are close to each other have a lower contrast.
Therefore blue and violet also have a low contrast.
Orange and green have quite a strong contrast as they are almost opposite on the colour wheel.
Red and violet have a medium contrast.
Contrast of saturation.
Formed by the juxtaposition of light and dark values and their relative saturations.
COLOUR EXPERIMENTS
These shades of green have a strong contrast of saturation.
Orange and red have a strong contrast of saturation.
These two shades of violet also form a strong contrast of saturation, one has a very strong chromatic value whereas the other does not.
These two shades of blue also have a strong contrast of saturation.
A low contrast of saturation is formed by these two shades of orange as they have a similar chromatic value.
These two shades of blue have a strong contrast.
Whereas these two shades have a medium contrast as the blues have a similar chromatic value.
The bottom shade of green is being used in this image, it forms a medium contrast of saturation.
Finally, these two shade of blue form as strong contrast of saturation as the base blue has a much darker tonal value.
Contrast of extension.
Formed by assigning proportional field sizes in relation to the visual weight of a colour. Also known as the contrast of proportion.

Firstly, the amount of blue balances the amount of orange. These two colours are complementary colours so would usually cause a strong contrast, but this is balanced with the contrast of extension.
Firstly, the amount of blue balances the amount of orange. These two colours are complementary colours so would usually cause a strong contrast, but this is balanced with the contrast of extension.
I increased the amount of orange to see if this would affect the balance. By increasing the amount of blue a stronger contrast is formed.
Finally, I increased the amount of orange again, in doing so the contrast started to become less intense again. More of one colour can be used to balance the contrast.
I started to experiment with the amounts of colour needed to create a strong contrast.
By increasing the number of orange lines the contrast slowly becomes more intense.
This finding was supported when I further increased the number of orange lines. The more lines added the more intense the contrast becomes.
Blue and yellow form a low contrast when placed in these proportions.
When the circle increases in size the colours become more unbalanced.
Balanced contrast of extension.
Balanced contrast of extension. More of one colour can be used to balance the contrast formed by colours. This works until the colours are balanced, at this point the contrast is at its harshest.
Contrast of temperature.
Formed by juxtaposing hues that can be considered ‘warm’ or ‘cool’. Also known as the contrast of warm and cool
A selection of warm colours on a grey background. Shooting these images with artificial light has affected the colours making them seem a lot darker that they are when viewed in sunlight.
Cold colours on a grey background.
Orange on yellow, these colours are both classed as warm colour so don't create much of a contrast.
On the other hand, this violet cd is classed as a cold colour and creates a strong contrast with the yellow background.
The orange and red circles are both warm colours and contrast the blue background.
Below I arranged a number of warm colored circles on a yellow background, there is no contrast caused by the colours.
Little contrast is caused between the yellow and green circles as they have a similar chromatic value.
A strong contrast of temperature is created by the violet cd and the red circle.
Finally, I experimented with trying to balance the colours by making an even arrangement of warm and cold colours. However this did not work, I would need to use the contrast of extension to help me balance warm and cold colours.
Complimentary contrast.
Formed by juxtaposing complementary colours from a colour wheel or perceptual opposites.
Complimentary colours such as red and green, or blue and orange have the harshest complimentary contrast as they are directly opposite each other on the Itten's colour wheel.
Red and green are complementary colours and have a strong complimentary contrast.
Blue and orange also have a strong complimentary contrast.
Furthermore, when a colour such as red is placed on a grey background it will create its complimentary colour, around the edges of the red circle i can see a green tint.
Blue creates an orange tint.
Additionally, yellow creates a purple tint.
I started experimenting with different colored backgrounds. I placed an orange circle on a blue background, the contrast is harsh and makes the orange really stand out.
Again, the contrast is harsh between red and green, if the contrast was to be less harsh the red circle would need to be smaller.
Finally, I also experimented with different colored backgrounds to see if this would affect the complimentary contrast between colours. First, I placed an orange and blue circle on a grey background.
Next I placed the circles on a black background. The contrast seems more intense because of the black.
Finally, I placed the circles on a white background, the intensity of the contrast on the white background is similar to contrast on the grey background.
Simultaneous contrast.
Formed when boundaries between colours perceptually vibrate.
I started this experiment by placing the blue circle on a grey background so I can gauge its chromatic value. It is a light blue but will work fine for my experiments.
When blue is placed on a blue background it looks dull and seems to have lost chromatic value.
Blue seem more vibrant on a yellow background as the yellow has less chromatic value so intensifies the blue.
The blue seems relatively unchanged when placed on a green background.
Moreover, when placed on a red background the blue seems dull, I believe this is because the colours have a similar tonal value.
Moreover, I also experimented with a grey, white and black background to see if this affected the simultaneous contrast. On a grey background the colour seems vibrant.
On a white background the colour appears to be more dull than when placed on the grey background.
When placed on a black background the colour seem vibrant.
The edges of each strip perpetually vibrate, I think this experiment works well due to the thin size of the strips.
I also experimented with green and magenta, although these colours are not complementary colours the also perpetually vibrate.
