Sienna

One of the types of oak trees here don't drop their changed leaves until spring, when the new buds push the old ones off, and strangely, every year they are a different color.  This year they are a sort of sienna color; the last few years they have been almost white.  I don't know what factors determine the color, but this section of a road I drive frequently passes a large grove along the hillside, and so it becomes a blur of sienna in my peripheral vision. 

This is my attempt to depict what I see.
