blauäugig

Etymology
From.

The metaphorical use (19th c.) is usually linked to the typically blue-eyed and fair-haired characters in naive, romanticist art. Compare. Perhaps the fact that newborns often have blue eyes may also be considered.

Adjective

 * 1) blue-eyed
 * 2)  innocent; naive, starry-eyed

Usage notes

 * In attributive use the word is always to be understood as "blue-eyed" unless the context implies otherwise. In predicative use the figurative sense is more common because one would usually describe eye colour by saying.
