Down

BLUE

Think of a color often linked to sadness or the sky on a clear day.

Down" is a clue that plays on double meanings—it can refer to a direction (like in a crossword grid) or a feeling of sadness. The answer "BLUE" fits because it’s a color but also slang for feeling low or depressed. The wordplay hinges on interpreting "down" emotionally rather than literally, making it a clever misdirection.
