The ColorFun project, led by MNEXT, has planned a larger-scale fermentation of a blue fungal dye and is preparing production of orange dyes. The dyes are made by fungi through fermentation of biobased raw materials, and the project studies production, extraction, purification and application together. First application tests with NPSP in biobased composite panels have flagged colour intensity and purification as areas needing work, showing what must be solved before the
