Vibrant Colors (RGB Table Replacements)
A mod that replaces the Color Lookup Tables in each stage with one that makes the colors more vibrant. Note that this may not affect every Cyber Space area, but otherwise if you wished the game had vibrant colors, then your wish has been granted.
Do keep in mind this is not a Reshade preset whatsoever. This actually modifies the game files.
