Colours of Autumn

I have been looking around for various examples and explanations of what colours people associate with Autumn below are the comments I have found and a song:

• A darker, richer shade of orange can be associated with autumn.
• Autumn brings rich colours everywhere, these rich colors are attributed to how the pigments in the leaves reacts that causes their colour.
• Colours of red and orange and yellow and brown.

• Put on your wellies and your overcoat
  Take an umbrella just in case you get soaked
  Because it's autumn and the weather's turning cold
  We're picking up pine cones and kicking up leaves
  We're waiting for conkers to fall from the trees
  Cos it's autumn
  And the leaves are turning red, yellow and gold
  The colours of autumn are red and brown
  The colours of autumn as the leaves fall down
  The colours of autumn are changing all around
  As the leaves fall to the ground

• The russet and gold leaves.

• As the chlorophyll breaks down the green colour fades revealing the yellow colour of Carotene, another pigment in leaves which was there all the time but masked by the chlorophyll. Carotene makes the leaves appear orange and yellow and as its name suggests is also found in carrots! As autumn progresses the red colour of another chemical might also be seen - Anthocyanin. This pigment only forms when the sugars become concentrated in the leaves as they break down, so ideal conditions for this are dry late summers.
