Hooking up my power switch/reset switch/LEDs

I'm working on building a computer (first time for me). There are several plugs that I need to connect to the motherboard (Power LED, reset switch, etc). Of the two wires, they are either:

1. Color and white (reset switch, power LED, HDD LED)
2. red and black (speaker, power switch)

The manual for the motherboard has a nice diagram of where to plug them in, but has them labeled + or -. Which colors are positive, and which are negative?

For reset swtich and power switch, it does not matter.

By electrical convention, red is positive, black is negative. For the others, generally I think colour is positive, white is negative.

For the connections you have listed, you will not damage your system if you connect them up backwards; the lights simply won't work.

In most motherboard cables there is a little triangle that marks the positive side. See the picture below:
