Using KYDS Scan Lines with KYDS Monochrome Palette

KYDS Scan Lines is designed to work alongside KYDS Monochrome Palette.

For example, you can combine:

KYDS Monochrome Palette Preset: GameBoy

with:

KYDS Scan Lines Opacity: 0.15 Spacing: 4 Thickness: 1

This creates a layered retro display effect:

Monochrome Palette

Scan Lines

Final Screen

The scan line plugin uses a separate PIXI overlay rather than replacing the monochrome filter, helping the two effects operate independently.
