What color is the hay?

The color of this plant is usually yellow or brown.

Hay is a kind of herbaceous plant, which has been dried at the end of its growth process, and its color will change from green to yellow or brown due to the loss of water during the drying process. This color change is caused by the decrease of chlorophyll and the relative increase of carotenoids, flavonoids and other pigments in plants.

In addition, the color of hay may also be affected by the drying process, such as the length of drying time, humidity and temperature of drying environment, etc. So the color of hay is not fixed, but will be different due to the influence of many factors.
