Translation:Her color is pink.
"Roze" is for plural words?
Well, 'pink' is always 'roze'. We don't have different forms of 'roze'...
Because the word was a noun before it was borrowed to be an adjective, it doesn't inflect like an adjective. This is the same for "rose" in French and "rosa" in German and Italian. (The modern Dutch noun is "roos", though)
How do you tell wether it is kleur or kleuren
