RAL 300 40 15

Muted Celery

RAL 300 40 15 Muted Celery occupies hue 300, lightness 40, and a moderate chroma of 15, a subdued mid-dark lime green that bridges fresh green and grey like the surface of celery stalks left to dry in autumn air. It is a natural choice for heritage structural elements, natural material colour coordination, and artisan workshop wall surfaces. The moderate saturation gives it a grounded, vegetable-garden quality that blends seamlessly with terracotta, natural stone, and weathered timber.
