When you go to the Star Wars parks at Disneyland or ??? ??? ??? ??? ??Disney World, there's a place where you get to craft your own lightsaber for the not-low-at-all price of $200. You get to build the hilt and choose your kyber crystal, which Star Wars geeks know determines the color of your blade.

Officially, you're only allowed to pick from the four colors seen in the movies: blue, green, purple, and red. Unofficially, you can actually make it any color you want.

Gene Chorba, a developer at Riot Games, tweeted Friday that those kyber crystals actually house a radio-frequency identification (RFID) tag that determines the color of the blade. With the right technology, you can actually rewrite the RFID to get a different color.

This Tweet is currently unavailable. It might be loading or has been removed.

That's right, you can get colors that aren't even seen in the movies.

All you need is an RFID reader/writer, which can be found online for as low as $20. If you want to see how to do it yourself, this video is a helpful tutorial on how to use an RFID reader/writer and how to change the color of the blade.

While Chorba tweeted out codes for two extra colors, orange (3074) and teal (3077), YouTuber Kyle Bridges lists a few more codes to make your blade white (3072) or yellow (3075) as well as the standard colors red (3073), green (3076), blue (3086), and purple (3079).

I neither have one of these lightsabers nor an RFID reader/writer to test this out, but the video proves that it works and isn't too difficult to do at home.
