Barry John RaybouldWhat is an imprimatura?
The imprimatura helps you judge values better, and can also provide a base for optical color mixing effects.
How to do it
Mix black with a little phthalo blue together with liquin or with a mixture of 80% dammar varnish 28% turpentine and very small amount (2%) of linseed oil (to prevent cracking).
The liquin makes the imprimatura dry quickly. Cover the canvas thinly, scrubbing the paint into the surface so that you end up with a transparent layer of a value of around six or seven (on the Munsell scale).
Color of imprimatura
I use a cool blue gray imprimatura because:
- it often approximates to a sky color, which is another reason I like to use this imprimatura so I automatically have my sky in place when I start.
- it helps me more easily judge color.
