Some basic notions illustrated by works of art

1. Colour

2. Primaries
The three primary colours
are yellow, blue and red.

3. Secondaries
When two primaries are mixed
together, they produce
secondary colours.
Blue + Yellow = Green
Yellow + Red = Orange
Red + Blue = Violet

4. Secondaries
So, mixing primaries creates
secondary colours.

5. Complements are the colours that
take opposite positions in the
colour wheel.

6. Complements
When complements mix, they
neutralize each other and grey
is eventually produced.

7. Colours are warm when they
tend to yellow and red,
and cool when they tend to
blue and violet
