Colour Theory

COLOUR THEORY

I began to research Colour Thoery. I found this to be an extremely interesting subject matter, discovering things we all take for granted every day in a new light. Throughout the following posts I hope to shed some light on the subject, making points from my lectures, as well as using research I have gathered myself from books and the internet.

HOW WE SEE

Before I understand how we see and interpret colours, I must demonstrate how we firstly use our eyes to see. Physically, we see using not just our eyes, but also our brains. Our eyes can only see the image, they cannot understand nor make sense of what they are seeing. The brain is responsible for sorting out all the information that comes through our eyes.

Above you can see that the image enters through the pupil and is reflected onto the back of the eye (Retina). It is then up to our brains to sort out what we are actually seeing. The image is in fact upside down when it reaches the Retina. This is because the eye is round in shape, and much like the lens of a camera, the image is flipped upside down.

PERSPECTIVE

Perspective is a precise, measurable illusion of the world. However, this is not how we see. It is a simple example of the relationship between the eye and the brain. Horizons are at 90º. We can actually see 15 miles into the distance. You will notice that your eyes are constantly moving and flickering, this flickering is our brain making sense of all the information it is getting. Our vision is in fact not determined by 1, 2 or 3 point Perspective, 4 point perspective is the closest representation to how we acutally see.. There are many types of Perspective. Here are the different types and some explanation of each:

1 Point Perspective

A Vanishing Point is one point perspective. We can only view things as far out as the Horizon. This was first discovered during the renaissance and for the first time ever, allowed artists to create paintings and drawing with real depth of perception.
