Idea for wiring.

Ok heres the Diagram





If I wired it up like that. Couldn't I flip a switch for what color LED's I want on?

So If I want red and green on. I flip the red and green switch?

and the same for the others?

yes you could wire them seperate. except your switch diagram is pretty messed up.

positive batt through switch to positive of the wire of the led box.

then the other 3 wires should be switched grounds, assume that they are all common positive and ground controlled.

oh oh oh...these are the million flat head strips

^^^ new diagram.

I would turn the BOTTOM switch on for the OTHERS to turn on as well.....

I did this like 5 years ago for my center console... seperate switch for each RGB color and the LEDs are in pyrimids of each color to blend them for different colors when different switches are flipped.

Instead of switches, could a person use variable potentiometers (dimmer switches)? That way they could have more than 7 colors.

The potentiometers were discussed here a while back.

If I knew where to get one locally I would have done this. Maybe I will shop around.

Yes, they could (in reference to the potentiometers). You can get them at a local radio shack.

I think this is what was mentioned before, but your bottom switch does NOT NEED TO BE GROUNDED, if you do that you will consistently burn wires/fuses, and none of your lights will work.

The 12V+ should go to the positive of the first switch, then the negative of that switch to the common positive of the lights. Then the individual negatives of each color should go to the positive of their switch, and the negative of their switch be grounded.

What do you mean by turn the bottom switch on for the "Others" to be on? The way I described above, the bottom switch will be a "Master" so that you can just turn the lights on/off, IE to keep your color combination on the switches.

I'm not sure how you excpect a wire to be controlled by the switch if it goes to the same terminal. Logically that wouldn't work. And then were is the ground in your diagram.

Wire the switches like corvettecrazy shows. If you wire it like you have shown, ever time you flip the switch on the +12V you'll blow a fuse. The reason is because once that switch if flipped, the +12V wire is directly connected to ground (ie short circuit).

If you're looking for potentiometers then go to digikey. They will have all the potentiometers you could want.

Bingo. Wire it like corvettecrazy has like mentioned above. You will have your ground switches and everything will work correctly with no shorts or anything. If you have anymore questions feel free to ask.......

Thanks
