Colour my world with the chaos of trouble;

The title is from The Boy with the Arab Strap in their song "Belle and Sebastian". It's the only quote I can think of at the moment that pertains the word "colour". Or "color" depending on which English you are used to. It's not all that random because today we are talking about and you guessed it: colour. Colour theory to be exact.

Terminology to be familiar with:

Hue basically means color. When we say "yellow", "black", we are talking about hue.

Value is the lightness of a colour. Lighter colour have higher value so we can say white has a higher value compared to black. In my research, it is noted that designs with high contrast value produces more aesthetically pleasing designs. This is a 2 minute drawing of a bee I did on Paint (don't judge me & yes, I noticed there's no wings) and it's evident that the yellow really stands out in from the black.

Saturation is how strong a hue looks. If a hue is desaturated, it would be look more grey.

Secondary colours are the love child of two primary colours. For example: Red + Yellow = Orange.

Tertiary colours are the products of two secondary colours. 

Analogous colours are the adjacent colours to a main colour and it's really not as complicated as it sounds. Just pick a colour and the colours on it's left and right and you have yourself a nice analogous colour scheme. Here's a nice chart to explain everything words couldn't.

Monochromatic colours is as simple as it sounds. Mono = one, single. It means different tines and shades in hue.

Tint is created when white is added to a hue, making it lighter while Shade is created when black is added to hue and thus making it darker than the original.
