I need to paste everything up, but I tested the 10 black dyes currently being made. Pictured at left is Lemon Yellow (Dharma) MX-8G at 4% DOS with 10 parts yellow and 1 part of 3 different blacks added (10% DOS). Black colors added to MX-8G shown from L-R are: 629, 602(a) and 275.These were the lightest, medium and darkest value from the process described just above. I will be repeating the same with reds, orange, turquoise, and some other colors. By the end, I will have a spreadsheet with the cast and sample photos..something to consider when you are dyeing certain colors. that color above on the far right is nearly Forest Green, NOT Chartreuse...to much blue, perhaps?
I got everything from Avocado to pea green and a very blue green...not 10 versions of of the Chartreuse I was expecting. When using black, the "cast' definitely plays a role in your final color. I will have a more definitive report and neater sheet up in a week or two. Our guild's bi-annual quilt show is coming up March 14 and 15 in Wauwatosa, WI - a Milwaukee suburb. So until then, this will have to do. All comments welcome. Any colors you would like to see the effect of the blacks upon? They are listed at the link
