controlling squares

I would like to hear any one's input on controlling squares. If you control say, the dark squares, does that not give your opponent the light squares???  sure, you can then place your pieces there, but you then give up the other color squares for your opponent's. Please, enlighten me because I feel like I'm missing something that seems to be of importance that I simply do not see yet. That is, I'm not sure how to determine which color to control, or how to go about using the squares to my advantage.

The answer lies in a gray area

Hey.  Here's a link to a guy doing a video analysis of a "dark square attack" -- some points I'd like to make about this...

It moves very quickly, don't hesitate to use the pause button. It's not for beginners.

I think this analysis is very good... I don't think you're going to come away from the video going, "oh, okay, now I know how to use a dark square advantage" ...but if you're ready for it, I think you'll come away from the video with a little more insight into how strong players think, in a practical way.... here's a real game with real decisions to be made... strategic considerations bump into tactical realities, and vice versa..

Good point wefedog...Perhaps the control of either white or black squares depends upon your oppents pieces ie blocking a bishop or backing up a knight. "Control is in the mind of beholder"

In my experience controlling a single color is defined by pawns. When controlling a single color is important, the pawn structure dictates limited access via a given color, and controlling that color controls the game.
