Here's something interesting for you, visual artists and curious people - an online test for color acuity in your eyes:
I remember taking this test a while ago and found it again, after making a little research on color acuity in various eyes in nature. So I decided to share it as well as give it another try. My eyes haven't been well lately as you know - the conjunctivitis is pretty much under control, but yesterday I've learned that I have to wear yet another minimally stronger lenses, now also coming with correction for some astigmatism o_o.... Yay for consequences of aging and not taking good care of myself!
Anyway, as for me, the test result is - just like it was before - a perfect 0 (the lower the score the better color sensitivity).
... I wonder however how I'd see the world if I was a bird or another creature that has a four-color or even five-color vision, rather than our puny three (humans are trichromats, that is - we have three types of color-sensitive cells that pick up three ranges of colors: red, green and blue. All the other colors we perceive are basically various mixes of those).
... How different would the world and my perception of it be? Or how different would it be if we could actually detect magnetism like some other animals?
Well, there are some articles around the web suggesting that there might be people (most likely women) that actually CAN see a fourth 'dimension' of color, but at this point it's nothing more than a speculation... that is otherwise researched (same with magnetoreception, actually -> www.youtube.com/watch?v=EbHSkZ…
That being said, the differences between color acuity can be vastly different on individual level (and we girls, generally have somewhat better color vision than boys) and it's still very fascinating to think hour our perception can be colored
simply by subtle differences between our eye/optic nerve/brain structure. Human perception is, in fact, an infinitely fascinating subject to study in itself.
... and one that actually should be an object of study for any aspiring artist on any field
P.S. And since we're on topic of eyes and vision, here's an appropriately thematic article with some interesting facts about the eyes: www.independent.co.uk/news/sci…
I especially like "A Vision Of The Future" paragraph of it, as it rises some interesting questions :3
