The change of Namco Lake from light blue to dark blue

From far to near, the weather changes seasonally.

1. Change from far to near: At the lakeside, Namco Lake is light blue, clear and transparent. With the distance from the shore, the color of the lake gradually becomes darker, from light blue to dark blue. This change is caused by the increase of lake depth and the decrease of suspended matter and plankton in the water.

2. Seasonal change of weather: The color of Namco will change with the change of weather and season. On sunny days, the lake will appear dark blue, while on cloudy days or rainy days, the lake will appear gray or green.
