This project was made to demonstrate the color differences between devices and software such as the Game Boy Color, Game Boy Advance, emulators or other GBC-compatible consoles.

It contains two main tests: Color Scene, which features several elements such as a house, trees, water, sprites and also 100% SMPTE bars for pure colors, and SMPTE Bars, which, as the title suggests, contains three groups of SMPTE color bars, 100%, 75% and 50%.

It also has a Flashing RGB mode, which flashes red, green, blue and white in rapid succession. To exit this mode, turn off or reset the console.

I’m amazed by that narrow font where you wrote Yellow and somehow made it readable
