Chameleon® Hydrochromic Inks & Coatings react to the presence of water. We make Reversible and Irreversible Hydrochromic Inks.

Irreversible :

We produce two types of ink.

  1. The first changes from a colour to white when exposed to water and remains so when dry again.
  2. The second dissolves and washes off the surface revealing a message below.

These irreversible inks are available in Blue and Black.


This ink is white in appearance but become translucent when exposed to water and then reverts back to a white state when dry.

The reversible ink is available in white only.

These products can be used in applications revealing that a product has been exposed to water, such as a mobile phone, through to interactive game cards that reveal images or messages either reversible or permanently.
