I typed "Katterna ar vit" i I see that some time's it's vita and vit so i'm wondering how I will know what one I use for the sentence.
Plurals get the -a, thus it's vita here.
Does that apply to all other colours?
Generally it applies to all adjectives. Some colors are special though. Rosa (pink) and lila (purple) never change, for example.
Thanks Zmrzlina :)
And when is 'vitt' used?
