Sennelier L’Aquarelle Watercolors are renowned for their luminous color, rich texture, and exceptional quality. Handmade in France with superior pigments and Kordofam gum arabic, these colors deliver brilliant intensity and remarkably smooth application. Sennelier’s signature use of honey not only preserves the paint but enhances its brilliance and workability.This enhanced formulation offers superior flow and blendability—perfect for both delicate glazes and bold color layering.

Rooted in the traditions of the Impressionist movement, Sennelier collaborated with artists from across the globe to develop a watercolor that captures the beauty of natural light. The result is a paint that offers vivid, transparent washes with rich, saturated color.

Pigment information

General reference notes about pigments can describe other media (such as oil). They do not verify this product’s exact formulation or behavior.

Cobalt Yellow

Pigment code
PY40
Type
inorganic
Chemical name
cobalt potassium nitrite
Chemical formula
K3[Co(NO2)6]·H2O or CoK3N6O12
Properties
Cobalt Yellow is an expensive, transparent, very pure yellow with only fair hiding power. It is reliable in watercolor and makes particularly good tints. However, it must be carefully manufactured in oil form, or it can brown. Cobalt Yellow is known for good mixing quality with all other pigments, and it is useful in glazes and for tinting.
Permanence
Cobalt Yellow has good permanence and lightfastness, and it can withstand strong sunlight.
Toxicity
Cobalt Yellow is highly toxic by inhalation or ingestion. The ingestion of this pigment has caused cyanosis (low oxygen levels in the blood) due to methemoglobinemia.
History
Cobalt comes from the Middle High German word kobolt, an underground goblin, because miners thought cobalt harmed silver ores. The discovery of the potassium and cobalt compound used to make Cobalt Yellow is credited to N.W. Fischer in Breslau in 1848. It was not introduced as an artists’ pigment until 4 years later, by Saint-Evre in Paris. During the previous century, it was considered the only color that could reasonably replace Indian Yellow.
