Acrylic Blox : Simultaneous contrast
Mounted Prints from Science Photo Library
Simultaneous contrast
Simultaneous contrast example. The green squares look brighter on the left, where they are in yellow bands, compared to the right, where they are in blue bands. There is no actual difference between them. This is a demonstration of the effect known as simultaneous contrast - the phenomenon whereby the perception of different colours is altered by their surroundings. There has been some debate - most notably amongst the 19th century scientists Helmholtz and Hering - as to whether this results from neurological effects or from retinal pre-processing. It is likely that it is a combination of the two

EDITORS COMMENTS
This print showcases the intriguing concept of simultaneous contrast. The image features a series of green squares, seemingly identical in color and brightness. However, upon closer inspection, one can observe a fascinating optical illusion at play. The left side of the photo reveals yellow bands surrounding the green squares, causing them to appear significantly brighter and more vibrant compared to their counterparts on the right side. Remarkably, there is no actual difference in color or intensity between these squares; it is solely our perception that is altered by their surroundings. Scientists have long debated the mechanisms behind this phenomenon. Pioneers such as Helmholtz and Hering proposed conflicting theories regarding whether neurological effects or retinal pre-processing are responsible for simultaneous contrast. It is now widely believed that both factors contribute to this visual trickery. This thought-provoking image delves into the realms of psychology, physiology, and neuroscience as it challenges our understanding of vision and perception. It serves as a reminder that our interpretation of colors can be influenced by ambiguous circumstances, leading us to question what we see before us. Science Photo Library has once again captured an awe-inspiring moment where science meets artistry with this print - an exploration into the enigmatic world of simultaneous contrast.
