Cloud Blue is the lightest blue color, dyed with indigo. I switched over from black beans to indigo in the late summer of 2017 and have been slowly converting ALL my blues. Indigo is light-fast and washes well. I treat it with two finishing steps after dyeing. First I soak it in a vinegar-water bath to balance the PH, a standard process. Next I soak the yarn in Eucalan to soften and condition the yarn.
