It was daylight when you woke up in your ditch. You looked up at your sky then.
That made blue be your color. You had your knife there with you too.
When you stood up there was goo all over your fur. Your hooves were sticky.
You wiped them on your grass, so now your color was green.

...

Oh Celestia, why did everything always have to keep changing like this?

Based off of track 69 of Undertow, Disgustipated and track 8, Flood.
Made for anticipation for the new T00L album.
Also, this may not make a lot of sense. It's not supposed to at first... You must seek for the deeper meaning...
