Riley, BridgetCataract 3
Bridget Riley is a painter from London who work was recognised since the mid 1960's. Her work has been associated with the Op Art movement. Optical illusions are abstract images. The interactions between the pictures plains are manipulated to create the illusions. The viewer is entertained by their understanding and what they are actually seeing. Illusions include movement, flashing, swelling, warping, hidden images and patterns. Mainly in black and white, Riley is on of the front artist who progressed with colour.
It is our own vision and human ability to see that makes exploring techniques within this movement so interesting, the retina for example records colour input differently as it receives the different light inputs. Manipulating this can create an interesting study.
In Cataract 3 waves horizontally drawn across the page by combining a wide arc with a very steep front to create hills sliding down the page in a south east direction. A uniform sequence with no mistakes.
Initially a black and white colour pallet is apparent that alternates between each block of wave. However within the image there is a red tinge diffused vertically and subtly across the eye line. The back turns more to a grey, then both initial colours make room for a new red line that echoes exactly the same movement. The intensity of the red changes, I think it has been mixed slightly with a black to change it's darkness as it gets closer to the top and bottom of the eye line. Resulting in an assimilation contrast.
Initially the images may remind the current generation of a faulty computer inject printout where the ink is low that gives red colour interruptions.
The artist has limited herself to a few elements a basic lines and a pattern. She therefore arguably has to be creative to produce a painting.

Colour interaction
(i) Simultaneous contrast
When one area of colour is surrounded by another area of a different colour. Initially it enhances the difference in brightness and/or colour. Also if the surround area is larger or more intense than the area it encloses, then the contrast is out of balance, resulting in exerting one of the colours.
(ii) In successive contrast.
One colour is viewed and then another, achieved by shifting fixation from one colour to another.
(iii) Assimilation contrast
The lightness of white or the darkness of black may seem to spread into neighbouring regions. Similarly, colours may appear to spread into or become assimilated into neighbouring areas. Resulting in neighbouring areas appear more alike
