On the contrary, you should draw attention to your location. Animals won't care what color the tent is, but if it's noticeable, people will see it. I'd much rather someone know that I'm there. It's the same reason hunters wear orange. It reduces the chance of bullets coming to hang out with your innards. A bright, unnaturally colored tent says "someone is camping here", while one that blends in says "all clear to shoot".I would imagine you would want the color to mesh in with scenery if you are somewhere "wild"? You would not want to draw attention to yourself or the tent.
The "be visible" folks all make good points, but I still prefer to stealth camp, personally. I used to backpack solo quite often, or with just my sister or a girlfriend. My goal under those circumstances is to not draw any attention to my campsite, which is always a distance from the trail. I don't care to have anyone dropping in to say hello. Every solo female hiker I know feels the same way. YMMV, hike your own hike, etc.
