Translation Traps (for Russian speakers)
- Do not translate as 'кадмиевый красный' in non-technical contexts; it will sound overly chemical. In general art talk, use просто 'ярко-красный' (bright red).
- Avoid confusing with 'кармин' (carmine), which is a different organic pigment.
Common Mistakes
- Misspelling as 'cadnium red' or 'cadmium read'.
- Using it as a general term for any red colour.
- Incorrect capitalisation (not a proper noun).
