I’m seeing red everywhere at the moment – from Santa hats to oversized novelty jumpers.
Now researchers may have found a way to see even more red, by modifying a colour-sensing pigment from the human eye.
Colour-sensing pigments in our eyes usually respond to wavelengths ranging from about 430 (blue) to 560 nanometres (red). However, the researchers were able to engineer a pigment to absorb much ‘redder’ wavelengths at 644 nanometres.
I wonder what Rudolph’s nose would look like if we could see this redder red…
