Green and yellow pigment developments.

This is an archived post from late 2017.

We have developed our production for certain transparent pigments to obtain a cleaner, more transparent paint film. The pigments have the same strength and the mass tone and undertones will appear the same. The visible difference will be increased glossiness and a more transparent finish.

  • Transparent Yellow Oxide
  • Sap Green Light
  • Nickel Azo Yellow
  • Golden Yellow
  • Golden Orange
  • Green Gold
  • Golden Green

from the Finest Quality lines will all be modified to the new process.

Aging additive mediums.

This is an archived post from June, 2016.

Retarders belong to Tri-Art’s collections of mediums classified as additives. Additives completely evaporate over time from the paint film and have no lasting effect on the final finish of the paints.

These products will naturally age and appear amber in tone. The aging or amber colouration will not affect the performance or alter the colour they are mixed with.

Improved umber pigments.

This is an archived post from June, 2015.

Tri-Art recently improved upon our recipe for grinding our umber pigments. We are using the same PBr 7 pigments but are now able to develop the colour further. As a result Burnt Umber, Raw Umber, and all the mixed colours using these pigments will benefit from this development. This applies for all our acrylic colour lines.

The more efficient use of the pigment also results in:

  • Darker and richer umbers than previous batches.
  • More intense chroma.
  • Stronger tinting strength.
  • Higher staining.
  • Glossier finish.

The following colours will show a slight shift in their mass tone and undertone:

Burnt Sienna, Neutral Grey, and Viridian Hue.


There is the same ratio of solids to liquids with each line. The colours will maintain the performance and ability associated with their line.

Improvements to our acrylic products.

This is an archived post from March, 2014.

Tri-Art has recently made significant improvements in the quality and performance of our entire range of acrylic products. After much testing and evaluation, we have been able to produce the best formulations for our product lines, achieving the same quality in terms of flexibility, adhesion, and resistance to yellowing with time.

We have been working towards these changes for some time, the implementation of which has resulted in the following improvements:

  • Glossier dry film.
  • Improved shelf life.
  • Enhanced colour staining power.
  • Increased transparency of dry resin (acrylic) resulting in higher chroma and pigment tone accuracy.
  • Improved rheology resulting in creamier wet film handling.
  • Augmented texture holding capabilities and brushstroke fidelity.

The dry film improvements have led to some physical changes in the appearance of the colours in their wet state. The wet to dry colour shift is most noticeable in our student lines.

Be assured that these colours, once dry, will have the same or greater chroma and pigment tone accuracy.
