Start by using a multimeter (they're inexpensive for the hobby ones) to check the voltage at the led when the unit is on. If you start with solar lights with AMBER bulbs in them, the voltage may be compatible with the red leds out of the chute, no major changes necessary. White DOES require higher voltage, and that higher voltage will damage your red diodes.
Taking out the old led will be easy as well...heating up the solder joints, and pulling gently. There will be a resistor in series, likely on the circuit board (follow the traces, you'll see it). Its value will be important in regulating the original led. Hook up 1 or 2 leds to the spot (in series, + to -, + to -) where the old led was. Both should shine when power is applied.
Why are they different voltages? The chemistry that makes up the diode itself is different in different colours, and each requires a different amount of power.
