Color Changing Game Boy Shell

| /

Are you having trouble deciding which color of Game Boy shell is best for you? We've decided to make that decision a little bit easier, by allowing you the option of two colors at once! These thermochromic shells transition between colors as the temperature changes, allowing a new dimension of freedom for your Game Boy color schemes.

If you're looking to go all in, try pairing one of these shells with our color changing DMG buttons, available here. We even offer NES-style color changing buttons here!


  • Trigger temperature : +- 22 Celsius / +-71,6 Fahrenheit
  • Durable ABS (acrylonitrile butadiene styrene) material from Japan 
  • Printed A, B, Start, and Select text
  • Manufactured for a perfect fit with the DMG PCB
  • Machine cast with a lightly textured finish to reproduce the feel of the original shells
  • High-quality replacement parts with an accurate fit


    • 1 x Color Changing DMG housing with matching battery door
    • 1 x Extension (link) port cover
    • 1 x Set of brand new screws 


    • Battery contacts and metal shield not included
    • Colors may vary from what you see on your display
    • This is an aftermarket product and may not feel identical to its genuine counterpart

    It's awesome

    I love this thing! Currently too warm out but it's will be awesome in all the other seasons. Nice colors as well. I wish there were some gor the other hand helds.

    Threshold seems a bit off

    I got the Purple Haze colour variant for this shell and while the colours are great and the colour changing is really cool, the threshold for changing seems appreciably lower than the nominal 22ºC. I haven’t been able to identify its exact threshold but the shell seems essentially stuck in “hot” mode at most reasonable room temperatures. It changes to “cool” mode in a refrigerator and outside on brisk early spring days, but would not change when placed in front of an AC set to ~18ºC. Still looks good stuck in green, though, and probably works better for the right circumstances.

    Item was not as pictured it was a straight purple not purple to pink and when I messaged about returning the item I received no response

    Hi Ben,

    Thank you for this review. We are sad to hear about the disappointment. Unfortunately, this shell is color changing, and does not stay as shown on the picture. We are sorry about the confusion.
