Readers may be interested in a new colour-related blog by the SDC’s Chief Executive Graham Clayton. The SDC – the Society of Dyers and Colourists – is the world’s leading independent educational charity dedicated to advancing the science and technology of colour worldwide. It is a professional, chartered Society and becoming a member gives access to SDC’s professional coloration qualifications. I have been a member since about 1982 and I am a Chartered Colourist and a Fellow of the SDC.
I also recently came across another colour blog called chromatic notes. It’s not clear from the web site who runs this blog but there is a great deal of technical information there.
