Have you ever waited at traffic signals after dark and observed how surrounding colours change depending on whether the signal is red or green? In “Wait” the colours of île de la Cité are also made bright by a boat’s high beam illuminating the arches under Pont d’Arcole. (We can’t see the boat but we know it is there.)
Here is a deep dark “Walk” (partner of “Wait”). Notice how light from the signal casts a different glow on the sky in each of the two drawings.
In recent posts I have been showing the oil pastel under-painting (before coloured pencil is layered on top). In comparing the under-painting stages of these two drawings (drawn several months apart) I see that this primary stage is now richer and more consolidated than it was in mid 2017. It is fascinating to chart the evolution of a new idea.
Next time you are sitting in your car waiting for the lights to change, or standing at a pedestrian crossing after dark, observe the colours as the lights go through their paces. (Trust me, it is more entertaining than merely being impatient.)
