With Kryptonite you can weaken Superman. The planet Krypton was more massive than Earth before it exploded. By bringing Superman into close proximity with a piece of Kryptonite, which is really a piece of his home world, you reduce (or in some depictions remove) his strength and ability to fly, which are the powers derived from his being on Earth.
There's still no telling how he flies in outer space.
All of the colors of Kryptonite would include Green Kryptonite, Red Kryptonite, Black Kryptonite, Blue Kryptonite, Gold Kryptonite, White Kryptonite, Yellow Kryptonite, Silver Kryptonite, Pink Kryptonite and Purple Kryptonite.
Kryptonite is Superman's weakness.
There is none. Kryptonite is a fictitious substance.

No, Kryptonite is a fictional mineral from the Supermanseries.
I'm guessing kryptonite.
Kryptonite Man was created in 2006.
Blue kryptonite - it improves Superman's health and frees him from red kryptonite's unpredictable side effects. Blue kryptonite only affects Bizarro - he feels weak.
Kryponite can kill superman, Magic can too. But doomsday actually killed him but he came back. I hate superman though.
