The new knowledge begins to fill the blank page. Things that once seemed strange and foreign now seem more natural. Natural is the color of the seed. A seed has been planted, and growth may occur. Yellow is the color of sunlight.
True growth begins as the seed is exposed to the sunlight.
Orange is the color of the sunrise and the sunset. Symbolically, the sun is setting on the beginning and rising on growing knowledge. Green is the color of new growth and the outer forest. New grass and leaves are bright green. They show promise of what they may become, but their roots have not yet developed enough to support full development.
