Lady Anachronism / Tetrachromacy

This blouse is entirely incredible. For the last few days, I've been pairing it with high-waisted shorts, skirts and polka dot dresses! It works with everything, and I can either tie it up at the waist or do up the buttons all the way down, which makes it a very versatile item!   blouse - c/o Choies dress - Vintage hat - c/o Wholesale necklace - Claire's (Japan) shoes - Vintage socks - Cotton On After I talked about colour vision in my last post, Emily alerted me to something called tetrachromacy, which I'm going to talk about here today! First off, most humans are "trichromats", meaning we have three different types of cells  (called cones) in our eyes that can detect three different wavelengths, or colour ranges. One type of cone detects red colours, one detects green and the last, blue. However, quite a few humans who have "colour-blindness", and many mammals (like dogs) are only "dichromats". This means they only have two types of cones in their eyes and so see a smaller range of colours than trichromats. Then there are some animals that experience more than the colours that we can see. Many birds and insects are what are called "tetrachromats", because they have four types of cones in their eyes. This means they are able to see all the colours we see (red, green and blue), plus a whole range of ultra-violet colours as well. And just as it would be impossible to describe 'red' to someone who is red/green colourblind, it would be impossible to imagine what the world would look like with so many additional colours. Theoretically, tetrachromats would be able to see millions more colours than we could see. They could distinguish between two shades of blue, for example, that would look identical to a trichromat. Although tetrachromacy has been said to exist (rarely) in humans, this has been hard to confirm experimentally (and there are claims that tests on so-called tetrachromats have been flawed due to insufficient blinding leading to the Clever Hans effect - something I'll talk about in a science post real soon). However, science may be able to turn people into tetrachromats. Scientists have been able to, via gene therapy, transform rats and monkeys who were only dichromats ("blind" to red and green colours) into trichromats. The method still needs some confirming, however if it does work, this technique could be adapted to allow colourblind people to see, and possibly even allow normal "trichromats" the chance to see in tetrachromatic vision! Which would be like having a mildly cool superpower, I think. (Read more about this in a very interesting article in the Scientific American). How are you all doing today? p.s. I have announced the winner of the Koogal giveaway! Thank you so much to all the people who entered and the awesome effort that you all put in! I was inspired by all the outfits people put together with Koogal items. Congratulations Ashley K. (I have sent you your voucher!)
