I am trying to wrap my brain around the DOS column on the chart 'Dyeing Trials for 5R 4/12' in the July 15th Power Point presentation. The Munsell notations for my Fuchsia and Scarlet dyes show they both increase in chroma as the DOS deepens. On the chart the 3.0% DOS dye bath is predicted to result in a chroma of 11. The 2.6% DOS dye bath is predicted to result in a chroma of 12. Wouldn't the chroma decrease if the DOS decreases for a dye bath using these two dyes? (We've demonstrated that some dyes have higher chroma at lower DOS.)
Also to confirm my calculations for a 3.0% DOS trial for 5R 5/12 (this is the color notation on my Munsell color wheel):
WOF 5g
DOS 3.0%
200ml water (40:1)
Total Dye 7.5ml of 2% stock
67% Scarlet - 5.025ml
33% Fuchsia - 2.475ml
From Chart: 2.8g of soda ash dissolved in 50ml of the water
12g salt
