Did you know that using the screen that you have you actually cannot get the color brown?
And in actuality brown isn't the only color you can't have. The fault lies in how our screens are built. And if you are I'm taking about modern screens which use pixels, and not those older ones which use electron guns to make an image.
As you should already know, pixels are made out of sub-pixels. These sub-pixels are red, green and blue. RGB, yeah. I don't know the order, there might even be a case of different orders for different monitors/screens.
Anyways, using these three colors, you can't get brown, you can get orange, and by dimming in you can get an orange that resembles brown.
And this is true for all colors, except red, green and blue. Every color of light except these 3, are 'fake'.
I forgot the thing I wanted to write about, so I gave you this shit.
