The next thing to do is to “open” the icon, using a transparent wash of yellow ochre paint as the underlying layer. I find that having this color underlying all areas of the image gives it a unity, and a warmth throughout. The yellow used for St.Tabitha is Yellow Iron Oxide.
I am using acrylic paints for this icon, and I use a very limited palette. It is not necessary to buy and use dozens of colors and pigments. Most of the time I use only 8 to 10 pigments, mixing every different color that I need. There are just a few “workhorse” colors that are needed, and the limited palette lends further harmony and unity to the image. Yellow ochre is an important color in iconography, so I have 3 different shades of ochre, and everything else can be mixed to order using these simple basic colors!
