I am trying to describe the color of the portion A in the picture shown above. My examples are as follows:
- In the bar, the color of the portion A is darker at a position closer to the center than at a position closer to the right end.
- In the bar, the color of the portion A is darker as the portion A is closer to the center of the bar than to the right end of the bar.
I am unsure whether my examples are correct because when I googled the expression "at a position...than at a position", I found only a few results. Could you advise me on my examples?
