Pink - part 3: Why can we see pink?

Good morning, Wednesday!

It's cold, not too late, and I'm at the university library with my first latte of the day, and ready for the second day at the last writing seminar before christmas. I'm happy with yesterdays efforts (I finished all my Pomodoros), but I do realise that this takes forever... I'm seriously hoping that during the next months my "output" will grow more or less exponentially, or it'll be very hard to finish my thesis by the beginning of September (OMG!). At least I have to dedicate more days completely to just writing, like I'm doing today and tomorrow (and yesterday!) ;)

- dress: Vila // west: Gina Tricot // tights: HM (200 denier!) -

One thing I don't like about the cold is that it becomes so extremely difficult to find something to wear - I freeze, like, all the time. But on Monday I found this dress at Vila that's comfortable, cheap (199,-) and since it's made by cotton I think it works very nicely with warm winter boots. When I'm outside I put a big sweater on top of it, and it just looks like the perfect skirt. I love that it's quite straight - it's a little loose around the waist (which I think is nice when I'm at work, and will be sitting for hours and hours), but a little tight around the derrière. With my west from Gina Tricot, it's a perfect, comfortable winter work outfit ;)

They had it in several colours (like dark grey, black, dark blue, and others), and I also bought one in orange. Now that I know how much I like it already, maybe I'll even buy another one.

Ok, over to todays title: the last guest blog post from my sister <3

(Read number 1 HERE, and number 2 HERE, to get the entire story about my favourite colour)

But why can we see pink?

Pink is a negative colour, if you will. When we look at a colour spectrum we see that the spectrum goes from gamma- to radiowaves, and visible light goes from red to purple, but nowhere is there pink. If an object absorbs all colours but green you get a sort of anti-green. Your brain interpret this as pink. Thus this is why we can see pink after all.

Lastly, I want to make a case for PINK. Even though pink is really a colour made by our brain, and not a real, visible wavelength, that doesn't make it any less of a colour. There are a lot of things that our brains make. Pictures and sounds are interpreted all of the time - that doesn't make the unreal! It is. however, neat to know how our brain works; if not for other reasons but to know what an amazing job it does every single day, and to understand how incredibly easy it is to trick a brain...
