The logo in the second video can be seen at 1:03

Logo: On a white background, we see the text "GAME BOY" appearing letter-by-letter, with rainbow colors scrolling through. When a cartridge is inserted, the Nintendo logo appears below it in black.

Variants:
 * Like the original Game Boy, if the cartridge is not inserted, the Nintendo logo is replaced with a black rectangle, however the registered trademark symbol is still intact.
 * Like the original Game Boy, if the cartridge isn't all the way in or is corrupted, the Nintendo logo is a mess of pixels.
 * On Japanese commercials, there is a flash with the text forming itself in a similar style to The Matrix.

Technique: 2D sprite animation.

Audio: The "bling" sound from the Game Boy logo when it is complete.

Audio Variant: On the Japanese commercials, a male announcer says "GAME BOY COLOR".

Availability:
 * Seen on all Game Boy Color games.
 * This logo is also used to plaster over the original Game Boy logo when starting up an original GB game on the Nintendo 64 and Nintendo GameCube.
 * Also used while playing classic Game Boy games on the Game Boy Color or Game Boy Advance (SP).
 * The best way to find a Game Boy Color game is look for a gray banner on the left side of the box with "GAME BOY COLOR" filling the rest of the banner.
 * It is also intact on Generation 2 Pokémon games when played on the GB Tower mode in Pokémon Stadium 2.
