A range of retro graphics in the style of old videogame consoles:

• Game Boy - Quantizes the image based on luminance and applies four configurable colors to those luminance bands.
• SNES (Posterize) - Quantizes individual color channels with individual bit depths (the SNES used different values in different circumstances, up to 8).

Parameters

• Enabled - When ticked, the effect will render.
• Drawing Mode - Which algorithm to use to draw the screen. Choose between Game Boy and SNES (Posterize).
• Power Ramp - Applies a power scaler to each color channel prior to performing any color transformations. Values higher than one will darken the image, while values lower than 1 will brighten it.

Game Boy

• Darkest Color - Color to apply to the darkest luminance band.
• Dark Color - Color to apply to the second darkest luminance band.
• Light Color - Color to apply to the second lightest luminance band.
• Lightest Color - Color to apply to the lightest luminance band.

SNES (Posterize)

• Red Levels - How many quantization levels to apply to the red color channel.
• Green Levels - How many quantization levels to apply to the green color channel.
• Blue Levels - How many quantization levels to apply to the blue color channel.
