Brindled, streaked, or multicolored
Bryndle is a modern American coinage derived from the English word 'brindle,' which describes a brownish or tawny color of animal fur with streaks of other colors. It follows the contemporary trend of turning descriptive nature-adjacent words into unique personal names by altering the spelling with a 'y'.
