Mixing french blue with acid dyes
  • I've seen a recipe for French blue with Procion MX, using Cobalt blue and Warm black (12:1 part ratio). However, I'm using acid dyes. Which Jacquard acid dyes would be best substitutes to mix a french blue colour?
  • Hi,
    I would recomend 625 or 626 with a little gunmetal or black.
