Colour Research Lab

About

Colour Research Lab was founded in 2017 in the Department of Textile Engineering, Mehran University of Engineering and Technology, Jamshoro Sindh Pakistan. The specific aim of the lab is R&D in colour science and applications. The lab was initially established in 2004 with the title of Colour Measuring and Microscopy Lab.
