Guest Blog Post by Anne Marr, Course Leader of BA Textile Design, Central Saint Martins and co-curator of the exhibition Real Dirty Blue. Real Dirty Blue brings together 26 designers who taught or studied on planet Central Saint Martins from 1927 to 2016. The title of the show originates from a well-thumbed dye book by wood block printer Joyce Clissold which offers a ‘live’ snapshot into 1930s textile alchemy: no two pages are the same, transcending a real sense of trial and error from the dye splatters that intersperse the notes and dye recipes. Colours have been labeled with witty names, leaving it open to imagine 50 shades of “Celestial Dirt” for example. This inspired Central Saint Martins’ Weave Pathway Leader Philippa Brock to explore Joyce’s “Real Dirty Blue” and she initiated a research investigation with Matthew Clark from the Society of Dyers and Colourists to recreate this true vintage recipe. Not familiar with some of the ‘antiquated’ ingredients such as Helio, Safflower and Auramine, Matthew matched them with today’s Colour Index generic names and was able to recreate the original shade. The results will be revealed in the exhibition together with many other fascinating textile projects – including highly inventive textile research and early prototypes, many which have not been shown in public before. The show has been curated into four key themes; 2D to 3D, Digital Pioneers, Happy Accidents and Material Artisans. Highlights include Malcolm Cocks’ vibrant 1990s digital prints, Nadia-Anne Ricketts' musical jacquard weave, Marta Velascos Velasco’s painterly sound tiles as well as Derek Lawlor'  s sculptural knit garments.
