Monday night I did a demo at the Port Moody Art Association using my seashells as a reference for a watercolor painting. I am working on a series of shells so thought this might fit in nicely for the demo and chose two larger images of my shells to hopefully show more of the detail while doing the demo. The painting is not finished but this is as far as I could get during the demo, whew!
The sand in the background had already been painted in to allow time to dry using yellow ochre, indian red & cerulean blue. The sky was then painted using cerulean blue, permanent alizarin crimson & naples yellow. I will likely develop both the sand and the sky a bit more once the shells are completed. The shells were then painted in using thin layers to build up the texture. The left shell was painted using burnt sienna, burnt umber & sepia for the stripes. Washes and dry brushed layers were added for the lighter areas using yellow ochre & burnt sienna.
The shadows were deepened using a gray created from cobalt blue, permanent rose & transparent yellow. This same gray was used for the right seashell with touches of burnt sienna for a warm glow. The dark shadows underneath the shell were created by mixing sepia with french ultramarine and painting several layers to built up texture and shape to the shadows. The final step was to paint in some highlights using Aquacover by Creative Mark. It is similar to gouache or white watercolor so you can use that instead but I prefer the texture of the Aquacover. I will post the updated painting once completed, I am calling it Lean on Me.
