Friendly Yellow SW 6680 and Full Moon SW 6679 by Sherwin Williams are two interesting colors. Friendly Yellow is bright and cheerful. It’s the kind of yellow you might see in a sunlit kitchen, bringing warmth and a sense of happiness. It’s a bold color that makes spaces feel inviting and cozy. On the other hand, Full Moon SW 6679 is very light and subtle. It’s almost like a soft white but with a hint of yellow.
