Perception 1

Colour is an interesting subject as we can't be certain about it. When you look at it scientifically colour is what our brains depict when we look around and light enters the colour receptors (cones) in our eyes.

Light can be reflected. For example; we see an apple red because it absorbs most of the incoming additive light (RGB) that hits it and reflects only the red light. Which is what our eyes pick up.
Or Emitted from a source and entering the eye.

Although, we must take into consideration that colour is not solely dependent on pigmentation but also dependent on the brightness of ambient light. Surrounding colours can also alter our perception of a colour.

Bellow are 2 squares of the same colour, both with different backgrounds. They may be the same colour but at first glance they seam to be of different shades. The square on the right looks to be lighter than the square on the left, yet they are the same. This is because a light tone looks lighter against a dark background than against a pale one.

This is another example i created. This time the two small squares are not of the same tone. Yet they seem to be, as the darker right square seems to be lighter due to the darker background.

It is interesting how colour can be easily confused, or more fittingly, confuse the brain. Bellow is a more complex illusion. what it seams to be, to the naked eye, are two different colour chest pieces surronded by fog.

Yet the two 'different coloured' chest pieces are one in the same. The confusion of black, white and grey surrounding and running through the chest pieces silhouette confuses the brain. It is a more complex example of the same above example i had created.
