scheele's green
C2Technical/Historical/Specialist
Definition
Meaning
A highly toxic, yellowish-green pigment made from copper arsenite, chemically CuHAsO3.
A historical pigment, now obsolete, known for its brilliant green colour and notorious toxicity, which caused illness and death among those exposed to it in wallpaper, fabrics, and paints during the 19th century.
Linguistics
Semantic Notes
The term is a proper noun (eponym) referring specifically to the pigment discovered by Carl Wilhelm Scheele. It is almost exclusively used in historical, art conservation, or toxicology contexts to refer to this specific compound. It is not a colour name in general use.
Dialectal Variation
British vs American Usage
Differences
No significant variation in meaning. Spelling retains the apostrophe 's' in both. Pronunciation of 'Scheele' may follow British/German (/ˈʃeɪlə/) or American (/ˈʃeɪlə/ or /ˈʃiːlə/) tendencies for foreign names.
Connotations
Identical in both varieties: historical artefact, danger, toxicity, Victorian era.
Frequency
Extremely low frequency in both, confined to very specialised discourse.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'Scheele's' (Шееле) as a common adjective. The term is a fixed name. The colour 'зелёный Шееле' is an inaccurate calque; the standard Russian equivalent is 'зелёная Шееле' or 'шеелева зелень'.
- Avoid confusing it with 'малахитовая зелень' (malachite green), which is a different substance.
Common Mistakes
- Misspelling: 'Sheele's green', 'Scheel's green'.
- Mispronouncing 'Scheele' as /skiːl/ or /ʃiːl/ (though /ˈʃiːlə/ is an accepted variant).
- Using it as a general colour term (e.g., 'I like that scheele's green dress').

FAQ
Frequently Asked Questions
No, it is obsolete due to its extreme toxicity and has been replaced by safer modern pigments.
It was discovered by the Swedish-German chemist Carl Wilhelm Scheele in 1775.
It contains arsenic, specifically in the form of copper arsenite, which can release toxic arsine gas under damp conditions or cause poisoning through dust ingestion.
Indirectly. You can see artefacts (paintings, wallpapers, textiles) where it was used, but it is not displayed as a raw pigment due to its hazard.
