Four effects you can achieve with Winsor & Newton mediums for oil colour


Artist Nick Scrimenti shared the important role Winsor & Newton mediums play in his work, you can read more about that here. Inspired by his pragmatism and exploration beyond his own immediate palette, we’ve chosen four mediums techniques that could expand your oil painting horizon.

After a layer of Artists’ Oil Colour has dried or semi-dried, you may choose to glaze it by adding a thin, oily transparent layer of paint. As light travels through the glaze, it’s reflected off the opaque layer beneath. In short, it makes the painting glow.

An often lengthy process of applying layer upon layer, glazing is one technique that benefits from a professional-grade medium, such as Liquin Original or Blending & Glazing Medium. If you choose to work with Liquin Original, you’ll notice an improvement in drying times and flow and less visible brush strokes. Blending & Glazing Medium improves transparency and depth, before drying to a durable, glossy finish.


Scumbling allows you to build up multiple layers of “broken” (speckled or deliberately cracked) colour. The base layer peeks through, giving a sense of depth, texture and colour variation to your work.

While the technique can be skilfully achieved with either opaque or transparent colours, the effect is stronger when opaque shades are used. The base layer needs to be thinned with Liquin Original, as it must be lighter than the upper layer.


Sometimes, blending a light area of oil paint into a dark area does not give off the smoothest glow. Many artists choose to add incandescence to their finished piece by using a stippling effect.

The best brush for stippling is one of our Artists’ Hog Brushes. Their stiffness, when used with thick, viscous colour, creates a strong, stippled texture. To achieve the most professional finish, mix your oil colour with Liquin Oleopasto, which will both extend and thicken Artists’ Oil Colour.


With its’ name coming from the Italian for dough, impasto is a particularly popular technique for exploring texture. By applying thick layers of paint with the right brush and mediums, brush strokes remain plainly visible and create a highly textured effect. Rembrandt employed this technique to pick out jewels on a costume, while Van Gogh used it for expressive purposes.

If you’re seeking an impasto effect, Liquin Oleopasto adds texture, thickens rapidly, dries to a matt finish and increases transparency. Liquin Impasto Medium, too, is designed to retain crisp texture but it dries to a slight gloss finish.

Whether you use Liquin Oleopasto or Liquin Impasto, your painting will be touch-dry in between one and six days, making both mediums particularly useful when layering for an ultra-thick impasto effect.

Whether exploring glazing or scumbling, stippling or impasto, be sure to refresh your knowledge of the three rules of oil painting.
