DMC Color Chart
Here we have a the DMC embroidery charts that diamond painting drills are based off of. Colors are sorted by shade. Colors are an approximation of what the diamond painting drills should look like. Of course, dye lots vary with every manufacturer and supplier. Shades can be quite "off" from the DMC guideline. Please see our Dye Lot Policy regarding color variations.
To find a specific color number, check the Numerical Chart and find the Column number (in the blue line). At the top of each section is the Column number for that shade.
What are the blank spaces? Those are DMC floss that do not pertain to diamond painting such as metallics, variegated, or pearlized floss.
