These packets come in colors such as blue for aspartame, pink for saccharin, yellow for sucralose, orange for monk fruit extract, and green for stevia, representing different types of artificial or natural sweeteners. To make the white mocha sugar-free, sweeteners like these may be added to the drink without contributing additional calories, mimicking a hint of sweetness typically provided by sugar.
