Both are commonly used and grammatically correct; the first sentence is a bit more complete.

Thank you for your help.

1. For example, red stands for Line 1, and green stands for Line 2. (subway system)

2. For example, red symbolizes Line 1, and green symbolizes Line 2. (subway system)

3. For example, red represents Line 1, and green represents Line 2. (subway system)

4. For example, red is for Line 1, and green is for Line 2. (subway system)

Are the four sentences the same?
Can we use other expressions instead of 'is for' as in the sentences above?

Answer 1

I'd use #4. All the others are not quite correct. The red and green lines don't symbolize anything. They are simply painted lines on a floor that lead passengers to the correct train for their destination.
