Back to Blog
so i've been thinking about writing a blog about color for a while. so, today's blog post will be my first if it kills me. ok. it's NOT going to kill me. (well, that's a little dramatic...)
but, if you're like me – the idea of starting something is, uh, well easier that actually starting something.
so, it's taken months to get here, but here we go. (by the way, in my head is the song from the sound of music "let's start at the very beginning".... so hum along if you know the tune.)
so... a blog about color. and if we're to start at the beginning – i feel i must start with a teeny bit of science. after all, when you find out what color actually is – it really does seem like magic. and for me, that's a huge is part of the appeal.
here's how this works. when light waves hit a red apple, the apple ABSORBS all the light waves EXCEPT red, and since the red light wave is basically "bouncing" off the apple, that's what we "see" or perceive – we SEE a red apple because the red lightwave is bouncing off the apple and "hitting" our eyeballs.
so, i think we need to back up a smidgen and just touch on what is light. i know this post is supposed to be "what is color" – so bear with me for a minute.
light from the sun is really a spectrum (a range) of colors that we usually identify as 7 different lightwaves – but we don't see them until they bounce off something, and then we usually just see one color. BUT, SOMETIMES we can see all the colors. are you thinking rainbow? if you are – you're right!
when we see a rainbow, we're seeing all the different wavelengths of light separate out into the visible spectrum (the colors humans can see) because the raindrops act just like a prism.
so, there ya go! now you can impress your friends because now you know what color is! at least you know a bit more now than 5 minutes ago.
to keep the learning going – here's a great lesson on color wavelengths from TED ed:
