From the Illustration Friday quote:
"Colour is my day-long obsession, joy and torment." - Claude Monet.
Looking at Monet's paintings side-by-side with countless copies, the originals stand out - the subtleties of colour which swallowed Monet whole, that he revelled in, chased, and tried endlessly to commit to canvas, those subtleties are lost in copies.
Instead of copying his paintings, to lose oneself in observation as he did, let us imitate that. Perhaps not to the point of obsession and torment - but how else to grasp at the joy he found in it?
