The human eyes have "only" 3 different colour receptors, so multiple spectra can be perceived as the same colour.
(And this without considering all the ways the signal is processed before you actually "see" it.) #Optics#Colour#Color#Vision
Before designing a website, or even making a small change to an existing one, ask if your design choices consider the needs of people with color blindness. Changing the button color on your website may seem insignificant, but it could make that website inaccessible to nearly 8% of men and 0.4% of women who have color blindness.
I was in hell and saw lost souls suffering. I went down a hill, hell was a century XVIII wooden house in victorian style all in white. I entered in, every room had a soul in torment.
Pleased to share my latest research "Zero-shot counting with a dual-stream neural network model" about a glimpsing neural network model the learns visual structure (here, number) in a way that generalises to new visual contents. The model replicates several neural and behavioural hallmarks of numerical cognition.
"A team of researchers have built a vision implant with tiny electrodes the size of a neuron, seeking to help blind people see again."
The Next Web reports: "Initial tests in mice showed that the implant can effectively stimulate visual perception using only a small amount of electricity."
