When you use more than one adjective to designate a single color (like "light blue," "dark green," "pale pink" etc.), neither of the adjectives changes according to the noun it modifies. For example:
Il a les yeux bleu clair et les cheveux brun foncé.
"He has light blue eyes and dark brown hair."
If this sentence were "I wear light blue jeans" it would be worded:
Je porte des jeans bleu clair.
But as the given sentence uses a "verb of appreciation", in this case aimer, then des changes to les.
Just as des does not require translation in my example sentence, nor does les in the given sentence.
If you wanted to specify a particular pair of jeans, you could simply say J'aime le jean bleu clair → "I like the light blue jeans.
But we are speaking of jeans in general here → les jeans plural.
There is also the likelihood that you would only use such specificity if asked. For example, you are in a store:
Q: Quels jeans aimes-tu ? A: Ceux-là. Les bleu clair
Q: "Which jeans do you like?" A: "Those. The light blue ones".
It would be nice if one of the Mods could double check my reasoning here.
It's not wrong. It's now been added and accepted.
The French sentence here can be a general statement about liking light blue jeans or a sentence that refers to specific pairs of jeans understood from context.
I wrote: "I like the light blue jeans" and Duolingo marked as incorrect!
when does "clair" translate to "light," and when to "clear"?
It depends upon the context in which it is used.
Le ciel est clair et bleu → The sky is clear and blue.
How do I distinguish between 'light blue' meaning 'pale blue' and 'light blue' meaning 'blue but not heavy'?
Light as in 'not heavy' is léger and not clair: les jeans bleus et légers.
Yes. It's best to learn it, so you will be understood by French people:
- love + things → adorer
- like + things → aimer
- I love light blue jeans → J'adore les jeans bleu clair
- I like light blue jeans → J'aime les jeans bleu clair
When a color is further qualified by another word, it becomes invariable. This means that two word colors like “bleu clair” or “bleu marine” will not agree in gender and number.
