I diluted leftover homemade blue food coloring (made with red cabbage and baking soda) with water. The food coloring turned the water dark blue, almost black.

After washing the fabric scraps in lukewarm water, all are only light blue. The beautiful teal color is gone.

For another dye sample I mixed red cabbage food coloring (the glass on the right) with soy milk (the glass on the left). I let the fabric soak overnight in the red cabbage-baking soda-soy milk dye bath. Before I washed the fabric it was turquoise like the dye bath, but after washing it’s just light blue.

All fabric scraps were bleached white cotton, pre-washed with soap and water and not mordanted.

Update: The dye samples aren’t very lightfast.
