If painting a lot with pale colours, you may choose to use Artisan Water Mixable Safflower Oil instead of Linseed Oil to reduce their consistency. It also increases gloss and transparency. Safflower Oil is slow drying and should not be used under faster drying layers, e.g. Fast Drying Medium, umbers etc. Please note: W&N Artisan mediums are designed specially for use with Water Mixable Oil Paints only.
