This sculpture started off white (the colour of the clay and then the gesso), then got a black base layer, was painstaking lightened to a chestnut brown, and then tuned to a fine dark mahogany brown.
Good question! And before I answer it, I'll briefly outline how I start painting my art pieces.
After a clay sculpture has dried out completely (a process that can take up to a week), I cover it in a layer of gesso (pronounced: jesso – as in “jelly”).
Gesso is a primer used by artists: it won’t yellow and is designed to cover a multitude of materials. It seals the surface and prepares it to accept paint. Gesso ensure that my paints adhere properly to the Creative Paperclay and won't flake off in the future.
Next, I spray several layers of acrylic to cover the whole horse. I do not use regular spray paints from a hardware store, many of which are solvent based and not necessarily designed for long-term reliability. I use a specially designed artist-grade acrylic paint in spray form by Liquitex. This layer can be any colour, but I often choose dark neutrals such as raw umber, black, or grey.
Once that layer is dry, I go back with a brush and touch up all the nooks and crannies with the same dark colour, except this time from a tube. I do this to ensure total and uniform coverage, so that no white from the gesso is showing anywhere.
Most of my sculptures are painted in a dark solid colour firstBut why?
This approach is similar to “laying a ground” or "toning" in painting. This means to put down a layer of paint on a canvas to give it a tone before starting the actual painting. I do it on my sculptures for several of reasons:
Laying down a toned ground isn't necessary, but it really suits my approach to painting my horse sculptures, and helps to create a depth of colour and emotion.
