class exercise

This is the first time color.i think it quite childish.
It's because just use as many as color on the picture.
However,never think of the structure.

This is the picture color by me after the lecture.
It's become more look good i think.
I can use the color scheme to color the picture.
I try to use 5 color scheme to color the picture.
It's really agreeable than the above picture.
Not only use all the color on the picture.
I hope i can use the color scheme more unbidden during my life.
