Multi-Color

Multi-colored LEDs will either have 3 individual diodes of Red, Green and Blue for RGB strips with an additional diode of White for RGBW strips. Each individual diode’s brightness is controlled using PWM dimming resulting in up to 16M possible color outputs.

You can, as long as the total load of the strips (total length x w/ft) is less than or equal to 80% of the power supply’s rated wattage capacity. And as long as they are off the same group, i.e single color OR Multi-color.

Whites under 3000K or colors close to a red light is best for sleep because they have a low color temperature, far lower than regular sunlight. You can be immersed in these lights at night without giving your body a jolt and altering your internal clock as blue lights or whites in the 6500K range could.
