RAL 130 75 30
Bright Sky Blue
RAL 130 75 30 Bright Sky Blue is positioned at hue 130, lightness 75, and chroma 30, a lively saturated blue that radiates the fresh brilliance of clear summer skies and sunlit coastal waters. It is widely used for children's space feature walls, creative studio interiors, and dynamic retail environment features. The elevated lightness combined with strong chroma produces a colour that feels both fresh and joyfully optimistic.
