In a rag weaving workshop, I remember the instructor saying that when you don’t like the colors in a design, it most often is because of value. And that’s the first time I heard of the Ruby Beholder.
Usually you just know if a color doesn’t go with the others, there are other ways to check the value in the colors we choose. I took a black and white photo, thinking of the gray scale, but you can use an actual gray scale finder. Still another way is to use red or green filters. The handy tools come to us mostly from the world of quilters.
While looking at my magenta yarns again the other day, I decided to get out the color wheel. When I pulled open the drawer that held it, I found something better, the 3-in-1 tool by Joen Wolfrom.
This tool has separate pages for lots of colors, from yellow green to aqua green, with all of their variations on little color rectangles on each page, AND there are also two filters, both green and red. If you want to read a bit more, all of the tools can be found on Amazon here.
