I washed the soft gray scarf seen in yesterday's post and the color is warmer now with some pinkish tones. Interesting, but I wish I could hang onto the cold gray tones. I have hard water. I neutralized the rust with baking soda then washed by hand in Ecover. Will take some experiments to discover why the color shifts. Not much I can do about the hard water. Not sure it is the culprit as I do a thorough rinse of the rusted silk outdoors with the hose immediately after the reveal and nothing changes then. I scanned approximately the same area as before.
