RAL 7040
Window Grey
RAL 7040 Window Grey is a light, cool grey that has served as a traditional choice for window frames, shutters, and exterior trim across European residential architecture for decades. This clean, professional shade provides a lighter alternative to the darker anthracite and iron greys while maintaining a modern, refined appearance. Window Grey is particularly popular in northern European countries where its cool tone complements the region's overcast skies and grey stone building traditions.
