7 Reasons Why Nothing Is Real And Your Life Is A Lie
4. Colour Doesnt Exist
Never mind the colour of the dress, all colour is an illusion anyway. When you look at something, you are seeing it because the light in the room is bouncing off it and on to the rods and cones in your eyes. You experience different wavelengths of light as different colours in your brain but, outside of the squishy mass in your head, the object isn't actually coloured. You could argue that those certain wavelengths are colour, but it's not even as as simple as that. Due to a little thing called "colour constancy", your brain is always adjusting and "filling in" the colours you "see" based on environmental factors. This is why an orange will look orange to you whether it is in bright natural light or dim candlelight. What's more, you can catch your brain in the act. The thing is, that you have very little colour perception in your peripheral vision so it is essentially in black and white, but your brain will fill in the colour for you. Get a friend (or an enemy, I'm not gonna tell you how to live your life) to hold up a brightly coloured mystery item in your periphery and try to guess the colour - it'll be tricky. Then, look at the object and ask them to move it back to the periphery, you should now be able to perceive the colour because your brain is "filling in the blanks".
