Red Cabbage Mood Paint

A working pH-indicator paint — purple, pink with vinegar, blue with soda.

Color
Purple, pink, or blue depending on pH
Binder
Gum arabic + honey

Boil red cabbage, reduce, and split into jars — each jar shifts color with vinegar or soda.

  • ▸Red cabbage is a natural pH indicator: purple, pink with acid, blue with base.
  • ▸You get three paints from one pot.
  • ▸Beautiful but fugitive — it's a paint that performs chemistry.

Steps

  1. 01

    Simmer chopped cabbage in just enough water to cover, 30 minutes.

  2. 02

    Strain off the deep purple liquid; reduce to a syrup.

  3. 03

    Split into 2–3 jars; leave one purple, add a drop of vinegar to one (pink), a pinch of soda to one (blue).

  4. 04

    Stir gum arabic and honey into each.

Materials
4

Notes

Fugitive — these will fade. Best for journals and demonstrations, not framed work.
