Demonstrating color transitions of leuco dye-based thermochromic inks as a teaching approach in textile and fashion design

Marjan Kooroshnia


Although there are a lot of interest concerning the use of leuco dye-based thermochromic inks in Textile and Fashion Design, there is still a lack of teaching approach to help students arrive at a better understanding of the color transitions of leuco dye thermochromic inks. This paper aims to share a systematic approach for teaching the behavior of leuco dye-based thermochromic inks to students in Textile and Fashion Design. Printed colorswatches and exercises were used as the central part of the approach. Through the approach it was described what printed color-swatches were and how to use them effectively to make color transitions understandable. The approach has been applied in several workshops at both Bachelor and Master level. The samples made by the students in the exercises clearly revealed that the approach created opportunities for students to craft an understanding of using leuco dye thermochromic inks through experimentation and individual exploration. Ultimately, this approach plays a fundamental role in the design process, the creation and the development of dynamic patterns.
