===Oversaturation===
[[File:1406913527173-1-.png|400px|thumb|right|'''Left showing the :''' The default game, and right showing .<br/>'''Right:''' The "Gameboy Colors" mode on [[VBA-M]] in "Gameboy Colors" mode.]]The original GBA Game developers often programmed a game's colors to be oversaturated by default. This is because the screen was on the Game Boy Advance is not backlit, so that the screen result would appear to be rather dark. To compensate for this, games would have very saturated and bright colors. The bright, overly saturated colors would appear rather look normal on the GBAhardware. In emulation, however, the this appearance of these colors are can be blinding and undesirable. Some games made after 2003 may look better with have also taken the backlit colors, however, as they were designed with the GBA Advance SP model in mindsince that one actually is backlit. For everything else, there are several ways to deal with this:
'''No$GBA'''
Under "Emulation Options", select "GBA Mode". There are four modes.
- GBA (no backlight) = strong desaturation
'''Shaders'''
There are Cg [[shaders]] which can be used in [[OpenEmu]] or [[RetroArch]] that adjust the colors to those of a real GBA screen, as well as other screen types. These shaders are additionally available in GLSL<ref name="GLSL">https://github.com/libretro/glsl-shaders/tree/master/handheld/shaders/color</ref> for OpenGL, and Slang<ref name="Slang">https://github.com/libretro/slang-shaders/tree/master/handheld/shaders/color</ref> formatsfor Vulkan.
For GBA, there is <code>gba-color.cg</code><ref>https://github.com/libretro/common-shaders/blob/master/handheld/shaders/color/gba-color.cg</ref>, which simulates the color profile of a GBA screen under an external light source more accurately than VBA-M or No$GBA color options. If you prefer the darker color options that those emulators have, then use <code>vba-color.cg</code><ref>https://github.com/libretro/common-shaders/blob/master/handheld/shaders/color/vba-color.cg</ref> instead.
