Etymology
The compound "blue-green" is a straightforward descriptive formation in English, combining two fundamental colour terms of Germanic origin. Both "blue" and "green" trace back to Proto-Germanic roots (blēwaz and grōniz, respectively), which themselves have uncertain Proto-Indo-European ancestry. The logic of the compound is purely additive, creating a colour designation that lies on the spectrum between its two constituent hues. This type of compound is common in English for describing intermediate or blended colours, demonstrating the language's capacity for precise visual description through simple lexical combination.
