This hue is inspired by the radiant yellow blossoms of the golden shower tree (Cassia fistula), the national tree of Thailand and a celebrated symbol of prosperity and renewal across South and Southeast Asia. Its cascades of bright, golden flowers appear in dense clusters, transforming entire canopies into waterfalls of color during the dry season. The yellow pigment comes from natural flavonoids and carotenoids concentrated in the petals, creating a vivid shade that glows under sunlight. In Thailand, the tree—known as Ratchaphruek—blooms during the New Year festival, its color representing harmony and good fortune. This brilliant golden-yellow captures the warmth, optimism, and regal beauty that make the golden shower tree one of the most beloved flowering trees in the tropics.
