Message: Thank you for your web site....I hope, it is one of the best web site about dye and dying. I need your help. Can you help me? Where can I get dyes which completely lightfast dyes and high lightfast value dyes. I also get information about lightfast dyes. 

I'm afraid that there is no such thing as a dye that is completely lightfast. All dyes will fade at least a little in direct sunlight or other intense light. 

I understand that the most lightfast category of dye is that of the vat dyes. This category includes the natural dye indigo and many synthetic dyes, such as the indanthrone dyes.

If you try a web search with the phrase 'vat dyes', you will see many commercial sources. For small-scale use by artists, vat dyes are carried by companies such as PRO Chemical & Dye (in the US; it does ship internationally) and Granat Farvekompagniet (in Denmark; also ships internationally). For contact information for these and other artists' dye supply companies around the world, see my Sources for Dyeing Supplies page.

(Please help support this web site. Thank you.)
