Green is usually a tricky color to use in web design. It doesn’t go well with very many other colors and it’s not always easy to pick the right colors to complement a design that uses a green background. Plantwithpurpose.org has made excellent use of a dark shade of green, blending it with red and yellow fonts and nicely matched alternate shades of green.

One of the key reasons the design of Plant With Purpose works is the simplicty of the layout and subtlety of the colors used to complement the background.
