1. Plant-Based Pigments

Derived from fruits, vegetables, and leaves, these are the most common natural colorants.

Source	Color	Key Compounds
Turmeric	Yellow	Curcumin
Beetroot	Red/Pink	Betalains
Spinach	Green	Chlorophyll

Why it matters: Heat-stable options (like anthocyanins from berries) work in baked goods.

2. Insect-Derived Colors

Surprisingly vibrant and historically used.

Cochineal (Carmine): Deep red from insects (ethical concerns drive alternatives).

Lac Dye: Purple-red, used in Asia for centuries.

3. Mineral & Clay Colorants

Inorganic but naturally occurring.

Source	Color	Use Case
Iron Oxide	Red/Yellow	Confectionery

Fermentation-based solutions are rising.

Spirulina: Blue-green, rich in phycocyanin.

Monascus: Red (traditional Asian rice ferment).
