deep green

Definition
Meaning
A very intense shade of green, often described as dark, saturated, or resembling the colour of dense foliage, deep ocean water, or emeralds.
Used metaphorically to describe an extreme or fundamentalist stance on environmentalism and ecological politics, prioritising ecological principles over social or economic concerns. It can also refer to a deep commitment to or passion for something green-coloured or related to nature.
Linguistics
Semantic Notes
As a colour term, it is compositional (deep + green). In environmental discourse, it's a fixed compound term often capitalised: Deep Green. The metaphorical meaning stems from 'green' as a symbol for environmentalism, with 'deep' intensifying it to denote radicalism.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'глубокий зелёный' for the political term; use 'радикальный эколог/экологист'. For colour, 'тёмно-зелёный' is accurate.
- Do not confuse with 'ярко-зелёный' (bright green). 'Deep' implies darkness/saturation, not brightness.
Common Mistakes
- Using 'deep green' to mean 'bright green'.
- Using 'dark green' for the political ideology (it lacks the specific connotation).
- Misspelling as one word: 'deepgreen'.
