Experiment with black bean dye. The ph scale is fascinating folks! 1st pic on left is black bean dye with a drop of vinegar. Note how it is murky purple on left of bowl and pink red on right-acidity in action Top right pic is 3 threads soaked in acidic dye and then washed in 3 different soaps to test their ph levels. The blue thread on right side is dish soap(alkaline). Middle thread is All dye/fragrance free -neutral? Left side thread purple blue is ivory bit more alkaline but not bad. Bottom pic is all 3 threads dipped in vinegar water rinse-they return a cool lavender shade.
