When I was working on the project for RIT, I experimented with creating some of my favorite jewel tone colors. I found that I could create a really nice range of bright and earthy colors. These are some of my favorite color combinations.
The wonderful thing about low immersion dyeing is getting the range of values and sometimes little bursts of contrasting colors that can pop up when the different color dye molecules haven't fully mixed. I love that dark olive color.
If you would like the recipes for any or all of these colors you can find them over at my other blog Painted Threads Projects.
