Global color bug
I found a serious problem, adding me to add a color as a global color. Then, if I modify this global color, and accidentally adjust its color to the color of an existing element, that element becomes a global color. You should rethink the definition of the global color. The global color should be the color style, not the true global color. There should be a distinction between global color and global color, otherwise it is really easy to make mistakes. I don't know if I described it clearly?
For example, if I have two rectangles that are red, a circle is purple. In order to facilitate the two rectangles to give the global color, now the color of the two rectangles can be adjusted uniformly. If I try to change the color, when the red color is changed to purple, the circle is also brought with the global attribute. If the purple color is changed to green, then the two rectangles and one circle are green, which is simply too bad. I just want to try to adjust the color for the two rectangles.
