The color is not random. The texture Offsets select which pixel from the texture to smear over the sides. If the Offsets fall between two pixels (0, the default DOES), then you get a smeared stripe with the top being one pixel's color, smearing to the bottom, being the other pixel. Same for right-to-left.
Repeat 0 can be useful, but you don't want to just use it willy-nilly.
I seem to have confused the board. Here's what I was trying to say .. sorry if it's repeated for you.

I made some examples.
First is "Your Texture" it's small, but it's just 4 colored squares.
Next is "What Second Life Sees". I tiled it to Offset (0,0) and scaled it up to smear things together. Notice how the center is a medium gray .. that is what Repeat (0,0) sees there. You could use TINY changes to the offsets to move the color smeared on the face away from that gray to one of the two-color-smeared areas or even into one of the just-one-color-near-here points.* Tad Carlucci sighs.
