Tri-Art Oil Colours are formulated as “Finest Quality” oils with artist-grade pigments that are milled for colour purity and brilliance in a thick-bodied format, so you can keep decisive brush marks and clean mixes without fighting a weak, oily feel; start by pulling paint straight from the tube for body, then modify only as needed for the passage, and explore the range here: Tri-Art Oil Colours collection.

Yes, they’re designed to be rich and thick in body, so for fine strokes or soft blends, load less paint and work it out with the brush before you add anything; if you need a true fluid mark, use a tiny amount of a compatible medium or solvent (general oil practice), add it gradually on the palette, and test on a scrap so the paint still “grabs” the surface instead of skating, and you can compare colours and sizes in the Tri-Art Oil Colours collection.

Tri-Art uses a refined sunflower oil vehicle to support clean, pure colour, and their own technical writing notes sunflower oil as an ultra-pale drying oil used to keep the paint film paler than many traditional options over time; in practice, that means you can judge mixtures more accurately while wet, and for bright tints and delicate greys, mix thoroughly and keep layers leaner early on (general layering principle) so the film sets evenly.

Build in thin, deliberate layers and give each one time to set before you trap it under a thicker application, as a rule of thumb (general oil guidance) keep early layers leaner and later layers “fatter” by adding more medium only as you go; Tri-Art notes their oils use driers to produce a stable, long-lasting paint film, but you still get the best results by letting underlayers become touch-dry before pushing impasto on top.

For clean-up, Tri-Art’s D-Limonene is positioned as a safer substitute for harsh chemical thinners, with strong cleaning power and less harsh odour; wipe paint out thoroughly first, then work a small amount through the bristles, wipe again, and finish with soap and water so you are not leaving residue near the ferrule, and keep solvent exposure and airflow sensible (general studio practice).

Tri-Art describes the line as an assortment using traditional and modern pigments, including a range of contemporary colours, so a practical approach is to start with a warm and cool of each primary plus a strong earth (for example an umber) and add speciality colours only when your subject demands it; mix strings (light to dark) before you start the painting so you learn each colour’s tinting strength, and browse options in the Tri-Art Oil Colours collection.

This is often a surface issue (general oil guidance): if your ground is very absorbent, the first layer can feel dry and grabby, so either adjust your surface prep next time or, in the moment, thin the first pass slightly and scrub it in as a stain layer, then paint normally once it has set; keeping early layers thinner and well-bound helps later strokes sit up cleanly, and you can keep your colour choices consistent by working from the same Tri-Art Oil Colours selection throughout the piece.
