Ask Jacksons: Are water-mixable oils as good as traditional oils in brightness of pigment and finished surface?

As with traditional oils, the pigment concentration of water-mixable oil paints varies from brand to brand. Professional-quality paints will offer the most luminous colour as they contain fewer fillers and have a higher pigment concentration than student grade ranges. Water-mixable oils tend to have a slightly glossier finish than traditional oils, but the sheen will also depend upon what mediums have been used. The finish of the painting can be changed with a varnish after the painting has been completed. Like in traditional oil paint, the finished painting should be allowed to cure for 6-12 months before a varnish is applied.
