Hey heres the riddle
What has six colors
Cant change its apperance
Usaully goes alone,yet sometimes is seen in pairs
Easiest to see when the sun is rising or setting
What am I

EDIT: I only play SL

EDIT: this is not a official contest you will receive you prize though but it might be a rare item though( I dont buy platinum need the money for other stuff)
So yeah the first three will get their prize I will announce the other prize receivers in later comments what they will get.
You will get only one prize even if you get the riddle right.
Oh and your last comment is the only one counted.
