The original Game Boy (DMG-01) didn't have a green screen filter — its LCD literally rendered four shades of yellow-green. This converter uses those exact values:
- #0f380f — darkest, the "black" of Game Boy pixel art
- #306230 — dark mid-tone for shadows
- #8bac0f — light mid-tone, most of the image lives here
- #9bbc0f — the pale "white" of the DMG screen
Every pixel of your picture is mapped to the nearest of these four using a perceptually weighted color distance, which is why the output reads as authentic hardware footage rather than a green-tinted photo.
Tips for the strongest Game Boy look
High-contrast pictures convert best — the 4-shade palette flattens subtle gradients. Set pixel size to 8–14 to mimic the DMG's chunky 160×144 resolution, and export at 2× for social posts so the pixels stay imposing.
Beyond the Game Boy
The same converter ships the NES hardware palette and PICO-8's 16 colors — see the full list on the picture to pixel art homepage, or read how palette snapping works in the pixel art converter guide.
