Lighting experiment #1: Two white LEDs and one green LEDs to make as a clear mercury vapor lamp

So I was thinking of this since orange LEDs can act as a HPS lamp. So I thought can two white LEDs, and one green LED make as a clear mercury vapor lamp, and it does! Correct me if I'm wrong on this. But this experiment was for fun, because I was bored. But yeah. Plus why are so many resistors but when theres only three LEDs? Because I had other LEDs to make this out, but the blue LEDs wouldn't make it as these three (two white LEDs, and one green LED) can.
