Which LED to use?

hi all,
im new to the forum
so hello

i was looking at designing a circuit that required two LEDs, having them in parallel, but functioning in opposite directions; one will be on with an input of a positive voltage (green) and the other with a negative voltage (red)

instead of using two different LEDs, I saw that I found possibilities of using 1
can someone help me with this?

I found something like this: VISHAY|TLUV5300|LED, 5MM, RED/GRN | Newark.com, but it is from a store in the UK, and I am not sure entirely how it works

thank you!

Like the schematic on the left?

This will do, ignore the picture, it will be in a white translucent case.
