Briefings

A 2026 study published in Matter & Light describes a new multicolored ink technology capable of switching visibility with specific light sources. The research suggests this could allow individuals to conceal existing tattoos during professional events or create temporary markings using a laser pointer. However, the safety and practicality of this 'on-demand' visibility remain unproven.

Key points

• The study, published in Matter & Light, introduces multicolored inks designed to change color based on different light wavelengths.
• The proposed application involves hiding existing tattoos or drawing temporary designs using a laser pointer.

Context and limitations

The technology is currently theoretical; safety protocols and long-term durability have not been tested or validated.
