Fair, in a way

The crossword clue is asking for a word that means fair, and is related to the word blonde. In this case, the word is likely ‘pale‘. When we refer to someone as being blonde, we typically mean they have light or fair-colored hair. So, if we were to describe someone as ‘fair, in a way‘, we could also say they are pale or light-colored. This makes sense both in terms of complexion and hair color, tying together both the clue and the solution.
