Kinda just something cool

I just wanted to tell you guys something i thought was cool. I had about 20 seed germinating and i forgot about them for about a week, then i planted them all outside and when they sprouted they were all green but then there was one that was like a darker more ashen blueish tint. I decided to transplant it into a pot and bring it inside to see how it turns out. I'll try to get pictures up and keep you guys updated on "her" devolpment.
