Yellow, Orange, Red: Pigment Descriptions
D277 Radiant Yellow
A high intensity blend of pure yellow pigment and white, excellent for use as a glaze or to portray optical effects of light and shade.
Vehicle: Alkali refined linseed oil
ASTM Rated: Lightfastness II, SEMI/TRANSPARENT
D225 Hansa Yellow
Also known as arylide yellow and commonly referred to as lemon, being a definite green-yellow. A particularly useful yellow for mixing greens. The precision of CAO formulas ensure you will be working with a high quality Hansa yellow with optimum transparency and fine tinting strength.
Vehicle: Alkali refined linseed oil

D201 Cadmium Yellow Light
One of the most important colors on your palette, this strong bright yellow covers well but its strength will allow reasonably clear layers when applied thinly. Absolutely lightfast, Cadmium Yellow Light dries slowly to a strong film.
Vehicle: Alkali refined linseed oil
ASTM Rated: Lightfastness I, OPAQUE
D283 Naples Yellow
Originally a lead based pigment, this pale yellow is a combination of cadmium and titanium pigments specially blended to produce a neutral, earthy hue. CAO Naples Yellow is a close color-match to that which has graced artist’s palettes for centuries, but without the harmful ingredients.
Vehicle: Alkali refined linseed oil
ASTM Rated: Lightfastness I, OPAQUE
D202 Cadmium Yellow Medium
A clean, bright medium yellow – reliable and handles well as is characteristic of all the cadmiums. Leaning more towards orange, it produces muted, yet desirable greens in comparison to the Hansa or Cad Yellow Light; dries slowly to a strong film.
Vehicle: Alkali refined linseed oil
ASTM Rated: Lightfastness I, OPAQUE
D228 Cadmium Yellow Orange
A brilliant and completely lightfast orange-yellow. While the level of low-grade orange pigments available in today’s market is astonishing, this color is actually a blend of two authentic cadmiums.
Vehicle: Alkali refined linseed oil
ASTM Rated: Lightfastness I, OPAQUE
D226 Hansa Yellow Orange
A valuable yellow-orange with particularly high tinting strength and good transparency. Also known as Indian Yellow in many artists’ circles, this color is completely lightfast and does not carry the negative connotations often associated with its inferiorly manufactured counterparts on the market.
Vehicle: Alkali refined linseed oil
ASTM Rated: Lightfastness I, TRANSPARENT
D204 Cadmium Orange
An intensely bright yet opaque pigment, its versatility allows for efficient coverage while at the same time reasonably clear layers can be achieved if applied thinly.

D245 Alizarin Crimson
Pure Alizarin – valued for its distinct mixing capabilities and transparency, must be used with caution as the Alizarin pigment, although universally recommended, has a poor lightfast rating.

Vehicle: Alkali refined linseed oil
ASTM Rated: Lightfastness III, TRANSPARENT
*A note on natural red pigments:
While all of the Classic Artist Oil pigments are inspected to meet the highest standards of quality, please keep in mind that many natural red pigments are not lightfast in and of themselves, and are only suitable for use as a full shade because they tend to darken or fade over time if tinted or mixed. There was a time in all paint manufacturers’ not so distant past, when large amounts of mercury and lead were often added to preserve color. Now that we know the dangers of these ingredients, we have removed these hazards from our formulas, and we can only hope that this process has been discontinued in all paint manufacturing. Nevertheless, the large demand of certain shades of red has not lessened, and though they are not entirely lightfast, you can still purchase these shades. We are proud to offer a number of superior, synthetic reds as alternatives in response to the demand for a high quality red pigment. Although not available to earlier painters, these reds allow for many of the sought after characteristics of the natural pigments, while retaining the superior lightfastness required by the professional artist.
