Yes. Especially that such a word doesn't exist.
While the feminine nouns have -ę ending in Accusative, the adjectives end in -ą.
Something I noticed. Czarną looks similar to a little English prefix thing, "carn". For example, carnivore, carnage... I don't remember exactly what it means, but it's something to do with meat and death. And black is a color commonly associated with death :>
