Dagny is a distinctive name of Old Norse origin, meaning new day. While not explicitly meaning blue, the concept of a new day often brings to mind clear skies and fresh starts, which align with a serene blue day. It is less common but highly regarded for its unique sound and clear meaning, especially in Scandinavia (Norway, Sweden, Denmark). Notable figures include Norwegian writer Dagny Juel and contemporary Norwegian singer Dagny.
