Tone and Value

This is a piece of concept art I have taken from the game Torchlight 2
and then I have grabbed all of the colours used in the piece and
put them to the side of the drawing.

Colour, Tone and Value

This is to show shading and shadow on
standardized 3d shapes.

There are three primary colours. Red, Blue and Yellow.

There are three secondary colours. Green, Purple and Orange.

There are 'Complementary' colours. They are opposite one another on the colour wheel.

The wheel is split in half around the Yellow and Purple areas.

A Tint is where a layer of white is added to the original colour.

A Shade is where a layer of black is added to the original colour.

Hue is another word for colour.

Saturation is how intense a colour is.

Value is how light or dark a colour is.

Monochromatic is the use of the same colour but with tints and shades to create other colours.

Analogous colour schemes are two colours directly close to each other on the colour chart.

An Equilateral triangle are a triad of colours like the primary or secondary colours.

An Isosceles triangle are colours which are called split complimentary colours.

A square on the colour wheel are complimentary colours combined with tertiary colours.

This is showing the variation in shades and tints. 

I have highlighted the different areas to show where the depth is and what is at the same level with what.

Green = Foreground

Red = Behind Foreground

Yellow = Immediate Background

Blue = Far background

The further away something is changes how strong the colours are of that specific piece of scenery due to the value being of a lower quality than the value of the foreground.
