Raspberry Pi Power Status LED Indicator

Question

Hey guys, I have recently gotten my new Pi 3.

I am loving it and am thinking of making myself a custom case for it.

However I have searched and searched and cannot for the life of me find out how I can wire up 2 LEDs in order to show the power status.

In other words, I want to find out how I can create a circuit that will have a red LED on when the Pi is off and a Blue LED on when the pi is on.

Thanks in advance.

PS: I am still quite new to the electrical spectrum.

That's a great idea for the push switch to safely turn the device off, something the raspberry pi would really benefit from! Once you export a gpio pin you can set the direction of the pin to be an output pin. Setting it's value to 1 will make it go high 3.3v and setting it to 0 will make it go low 0v. I haven't checked for certain but I would assume that the pins are always low when the raspberry pi is powered down so it should be simple enough to work a solution with indicator led's
