Note on select colors - Raw Umber, Raw Sienna, Burnt Sienna, Indian Yellow, Permanent Tuscan Earth, Olive Green, and Sap Green were originally formulated with mineral spirits, which may result in a slightly stronger scent. This does not affect the quality, performance, or permanence of the paint.
The formula has since been updated to remove mineral spirits. Due to mixed stock, you may receive either version. If you prefer a consistently low-odor option, consider Utrecht Artists' Oil Paint .

Phthalo Blue PB15:1 is a structural variant of Phthalo Blue PB15 that produces more reddish tones.
Phthalo Blues are completely lightfast and stable and are permanent for all paint uses. They are currently used in inks, coatings, and many plastics due to their stability and are considered a standard pigment in printing ink and the packaging industry.
Developed by chemists using the trade name Monastral Blue, the organic blue dyestuff now known as Phthalo Blue was presented as a pigment in November 1935 in London. Its discovery was accidental. The dark color was observed in a kettle where a dye was being made from a British dyestuff plant. The demand for such a pigment came from commercial printers who wanted a cyan to replace Prussian Blue.
