This piece by Ryodi Ikeda : point of no return, a pulsating stroboscopic sound and light installation, appears to be monochrome. However images captured digitally reveal a more nuanced colour spectrum.
It is suggested that the human eye is capable of perceiving between 2 and 3 million colours, whereas birds, butterflies, fish and bees can see many more. Jennings explains that this is related to a difference in number of photoreceptors or cones. Humans with three cones are trichchromats whereas the birds and bees have four and are tetrachromats. Research on gender differences colour perception suggests that some women may also be tetrachromats. When contemplating the significant variety in our environments its intriguing to imagine what else might exist beyond our perception.
