Experimenting with grisaille and glazes

Painting by Vicky Christensen, acrylic on 18 X 14 inch canvas 

I wanted to experiment more with the grisaille technique. I created a grisaille underpainting with black pastel, glazing liquid and titanium white paint (see below). After it was dry I 'colorized' it with glazes of transparent paints and glazing liquid.

This painting started with drips of diluted fluid acrylics on a canvas prepped with clear gesso. I dropped the paint after brushing water on the canvas and let the color flow. After letting it dry overnight I drew the flowers and branches with a black pastel pencil, then started to paint and glaze. I used some micaceous iron oxide paint to darken the periphery.

I finished the still life. Here is what the pastel/glazing fluid underpainting looked like before I started glazing on the color:

My optometrist says I have cataracts  (not too advanced yet, very common at my age). She says when I reach the stage where I have them removed, colors will suddenly look much brighter. I'm wondering what this painting will look like then. I can't imagine it being more colorful!
