You stand at Five Flower Lake and try to understand what colour the water is. Turquoise, blue, green, and gold simultaneously, depending on the angle of light. Autumn trees reflecting in it add red and orange. The bottom is visible at 30 metres depth. The colour comes from calcium carbonate deposits and light refraction. The UNESCO World Heritage Committee inscribed it in 1992. No photograph captures all the colours at once. For the Chengdu context: Day Trips from Chengdu.
