Color Changing Game Boy Buttons (NES Style)

Retro Modding

Imagine having the power to change the button color of your Game Boy or NES controller at your fingertips. Or don't imagine, because you can now experience that power for yourself! These thermochromic buttons transition between colors as the temperature changes, allowing a new dimension of freedom for your Game Boy color schemes.

There's no need to stop there. Take your color variability all the way, with our color changing DMG shells, available here!

Beautiful Buttons that shift colors as you play!

These buttons look great in Retro Modding's clear NES controller shells, and I love the color shift based on temperature. High quality molds as always. Wish more colors would come out!

I'm not sure how they change color

They are purple. I've never seen them as another color. Functionally, they are fine.

Hi Kevin,

Thank you for this review. These buttons can be a little bit confusing. The color will change with temperature. To see the difference, you can try to put the buttons in the fridge for a couple minutes.
