What are the real Game Boy Pocket "colors"?

[Nemau]

Hello everyone!

Are the GBP "colors" (the four shades of grey) transposable to RVB system with a safe system/program? (I mean: not by just looking a GPB screen) And, if "yes", what are these colors?

I'm ripping all the maps from Link's Awakening and I want to give them the real colors (if they exist in RVB mode).

Thanks!

First off, just to be clear you probably mean RGB; in French it's rouge, vert, and bleu, in English it's red, green, and blue.

We had a thread about this before, it was about the GB instead of GBP but the only visual difference is that the GB had a green tint. I'll explain it again here though.

The console uses 2 bits for its colours, which is 4 colours total:

00 = 0
01 = 1
10 = 2
11 = 3

0 is black, 3 is white, and the others are the intermediate greys. Therefore in terms of RGB codes they would probably be:

0 = #000000
1 = #555555
2 = #AAAAA
3 = #FFFFFF

Emulators will use whatever they deem looking best but this is what I assume are the "true" colours. That said, the GBP itself doesn't use RGB, so technically speaking these are just what are mathematically most correct.

Ok so this mean the GB(P) use the most black, the most white, the first grey is "1/3 white" and the second second one "2/3 white". Thanks!

Oh, yes, sorry. ^^

Merci pour la bonne publicité des français :-), mais il faut quand même avouer qu'on dit toujours que les français sont les plus mauvais en anglais, sans aucune explication rationnelle. Anyway, passez un bon séjour ici.

Forgive me english speakers by using the french language, but what I told wasn't linked at all with the topic of this thread, except this :
The sprite data is writed using the 2 bits, so you cannot extract other color values. But in some GB games, the Game Boy Player use a custom frame and some recolour for the game.

Well, it does have 4 colors, but those colors are not well defined. The first gameboy had a green-ish screen, and also lacked any sort of backlight, so all colors looked like some shade of dark green/black. The GameBoy Color on the other hand, had a colored screen, and when playing the classic GameBoy games on it, switching between different palettes was possible by pressing a button combo at boot. On the Super GameBoy (that allows playing GameBoy games on the Super Nintendo), it would choose the most appropriate colors based on the game. Current emulators will let you configure whatever you want, but they usually use the Super GameBoy colors when possible.

So, what are the real GameBoy Colors? That's a good question. I think for sprite ripping purposes, 0/3, 1/3, 2/3 and 3/3 of white is fine.
