This time of year, between the position of the sun in the sky and the long daylight hours, there’s lots of light bouncing off the sea in the afternoon as the sun heads to the horizon. Little wonder then I’ve found myself reaching for iridescent pearl not only for my current silver birch painting but also my Minch seascape paintings-in-progress. It conveys the silvery glare beautifully and works both in the top layer and lower layers. A little can be quite determined to show through layers! Depending on the light falling on the painting, and your viewing position, you may see lots of it or you may see nothing at all.
