What it shows on the island
From holidays.yml:
Smiling summer sun with shades.
Sprite
Dimensions: 32 × 32 pixels. Anchored at island position (404, 284).
Added by this port via the holiday expansion. existing_sprite: null. The visual is a 32x32 transparent emblem authored by an AI sub-agent in the shared 16-color CLUT defined in scripts/holidays_art_lib.py. It overlays the island corner during the holiday’s window rather than reskinning the scene.
Palette
#5AD0E8, #FFD93D, #FFFFFF
Three-color hint from holidays.yml. This is a guide for the codegen step and the emblem authoring pass; the actual emblem samples from the shared 16-color CLUT, and the original Sierra sprites use the original game palette directly.
Algorithm
