I figured out a strange thing about green. There are red stars, orange stars, yellow stars, white stars, and blue ones. A graph showing how much light is emitted at each frequency/color explains the variety. The temperature determines the peak frequency/color. Cooler stars have their brightness peak in the red, hotter ones in orange and yellow, and very hot ones in blue. Our sun is brightest in green. Our eyes and brains have evolved to see a mix of colors dominated by green as white. But it is actually mainly green light.
Plants use light to produce food and to grow. The more light they gather the better they can compete and flourish. Which is why they are green - because the sun is brightest in green. The true color of the sun is the color of the leaves outside your window.
