Area effect cloud particles from creeper explosions are incorrectly tinted

When a creeper with a potion effect explodes, the resulting area_effect_cloud spawns pink particles -previously black from 24w11a to 24w12a (MC-269427) - instead of using the potion effect's tint. Likely due to recent changes in potion data.

Steps to reproduce:

• Spawn a creeper.
• Splash it with a potion.
• Blow it up.
• Everything is pink.
