One of the things I've discovered about fall foliage is that its beauty is more than bright colors. Sure, red, yellow and orange are the stars of autumn's display, but there is great beauty in less showy shrubs and trees. To me, there is art and beauty in all stages of the death of blooms and plants. Form, shape, light and texture all play into the spectacular show that Mother Nature puts on for us each fall. And I think that's a little more noticeable right before all of the leaves turn and the colors hit us with their full force.
Of course, a little color doesn't hurt.
