Depth of field using colour

These images illustrate the way colour can be used to create depth of field. Hue, saturation and value can be used to create depth of field:


Hue - Warm reds and yellows make up the foreground cooling to greens and blues in the distance.
Saturation - Bright colours in the foreground fade to grey in the distance.
Level (shade) - On a dark background start with bright colours and darken into the distance.
Level (tint) - On a light background start with dark colours and lighten into the distance.
