Thanks for guessing but you're all wrong ...............the flowers are yellow. 
"The appearance of mung bean plants is more similar to garden beans than it is to soybeans. They can grow up to 24 to 30 inches (60 – 75 cm) tall; they also have smaller leaves than soybeans, and a moderate number of branches.
Pods are three to four inches long, with 10 to 15 seeds each, and there are 30 to 40 pods in every plant.
The color of the pods turns darker as they mature, making it easy for growers to known when harvesting time is nearing."
