You would use the adjective formed from the past participle of the body part cast as a verb.
long-legged bird
pigeon-footed runner
blue-eyed dragon
long-eared rabbit
long-haired dog
saber-toothed tiger
double-edged sword
and so forth.
This form will always be grammatical. In some cases, e.g. saber-tooth tiger and double-edge sword, you will hear the adjective being formed from two nouns in combination. This could be a case of the 'd' being dropped for phonetic simplicity, since it tends to happen where the resulting consonant cluster is a little hard to pronounce. We wouldn't say "a brown-eye girl".
If the question is specifically about a particular playing card of some kind, and not about the grammar of adjectives involving a body-part or attribute, then some other rule may be in effect.
