I used the 10:1 mixtures last week to dye the 'Boring Beige' formula. I had a good bit left over so saved it. I left town for 5 days then returned to the dye room. I made my other 2 'Boring Beige' samples. The color was entirely different. We have so much humidity here in the summer I never considered the mixtures would evaporate, but I think that is exactly what happened (air conditioning). I had used the navy to make some other samples, so had a fresh amount of it. I think that is why the color is so skewed to the red/gold range. I love the coppery color, will do the Munsell notation and try to duplicate it. Overnight I left another jar of 10:1 solution just to see and, sure enough, this morning there was a ring around the top of the liquid as a 'high water' mark. I hope this saves someone else from making this mistake. The two silk organza samples are on the left. The two silk paj samples are on the right.
