For specific models of videogame consoles, simulations of how the sample image would render in different graphic modes are provided, if available. These simulations are always up to the maximum vertical resolution of the given graphic mode or up to 200 scan lines, if vertical resolution is greater. So any of them could be properly padded, transcoded and dumped into the original hardware and/or software emulators without any other changes.

The sample images only try to show how a certain system is able to handle to an image in terms of color without improvements nor additional clever tricks of design like anti-aliasing

 has a 15-bit RGB (32,768 color) palette, with up to 256 simultaneous colors.


However, while the hardware palette can only contain 256 entries, in most display modes the graphics are arranged into between 2 and 4 layers, and these layers can be combined using additive or subtractive colour blending.
Because these blended colours are calculated by the hardware itself, and do not have to be represented by any of the existing palette entries, the actual number of visible colours onscreen at any one time can be much higher.

The exact number depends on the number of layers, and the combination of colours used by these layers, as well as what blending mode and graphical effects are in use. In theory it can show the entire 32,768 colours, but in practice this is rarely the case.

Original Game Boy

The original Game Boy uses a monochrome 4-shades palette. Due to the fact that the non-backlighted LCD display background is greenish, this results in a green-scale graphic display, as it is shown in the simulated image (at Game Boy display resolution), below.

 systems uses a 15-bit RGB (32,768 colours) palette.

When an older monochrome original Game Boy game catridge (Type 1) is plugged-in, if certain combinations of the controls are held during startup, the games are colourised with one of the factory 12 false colour palettes. In this mode, games can have from 4 to 10 colours, due 4 are for the background plane palette and there are two more hardware sprite planes palettes, with 3 colours plus transparent each.

The following shows these startup palettes (background plus both sprite planes) and the combination of controls used (the names are taken from the Game Boy user's manual; the colours are simulated):

UP (Brown)

UP+A (Red)

UP+B (Dark brown)

DOWN (Pastel mix)

DOWN+A (Orange)

DOWN+B (Yellow)

LEFT (Blue)

LEFT+A (Dark blue)

LEFT+B (Gray)

RIGHT (Green)

RIGHT+A (Dark green)

RIGHT+B (Reverse)


The specific Game Boy Color (Type 3) game catridges presents up to 56 colors without the use special programming techniques from the full 32,768. From these, 32 are for a background palette, plus 8 hardware sprite palettes, with 3 colors plus transparent each. Typically, the sprite palettes shares some colors (black, white or others), so the total colors displayed are less than 56.

Here is the sample image shown in the non-backlighted color LCD display of the Game Boy Color (the colors are simulated):


Though there is a 56 color limit, this in of itself is a palette storage limit and not an actual hardware limitation. As such, the programmer can swap out the palettes on a per-scanline or even on a mid-scanline basis ("mode 3 mid-scanline rendering"). Because of this ability to swap out the palettes each scanline, over ten thousand colors can actually appear on screen per frame when programmed on a per-scanline basis.
