Green
The color green is almost exclusively used in connection with plants in the Bible, and the meaning is closely connected to the meaning of plants as well. Plants, in general, represent facts, knowledge that we can gather from the world. Green plants are ones that are alive and growing. Since life represents love and goodness, it makes sense that green plants are facts that have the potential for good use. It also indicates that they are the kinds of things we learn through directly through our senses, since to identify green plants we need to actually see the greenness.

Deuteronomy 21:11-13
11
and see among the captives a beautiful woman, and you have a desire to her, and would take her to you as wife;
12
then you shall bring her home to your house; and she shall shave her head, and pare her nails;
13
and she shall put the clothing of her captivity from off her, and shall remain in your house, and bewail her father and her mother a full month: and after that you shall go in to her, and be her husband, and she shall be your wife.
