SCIENCE | Can you spot slight changes in color? Take the Color Test.


Are your eyes sensitive enough to differentiate a slight change in color? Taking a color test will let you know how hard or easy it is for you to detect colors that vary in hues. Who knows? You could be one of those ultra-sensitive enough to figure out one shade from the others!

Online content creator Buzzfeed came up with this short video that lets you know how good you are when it comes to color perception. As for the results, I got all 23 letters right! How well did you fare?

So, you may ask, how do we see color?

Cones in the retina found at the back of our eye are the ones that receive and respond to the light waves that reflect from a surface, e.g. that of an apple. When light coming from the apple hits our eyes, it stimulates these cones (red, green, and blue) to some extent. The stimulated cones then transmit the signal along the optic nerve na nagkokoneta papunta sa visual processor/interpreter ng utak natin -- the visual cortex, which then returns with the color red.

We humans are far superior than most mammals when it comes to discerning color, BUT there are some animals outside our turf na mas magaling pa sa pag-perceive ng color. Examples are birds and fish which have more cone types (four rather than three) that allows them to see ultraviolet light or any type of light with wavelengths undetectable by our eyes.
