For a one-page printer-friendly text description of all colors:
If you do not see a difference between the two skeins, your monitor may not be correctly adjusted.
Adjust your monitor so you can see 18 shades from white to black.
You should also see 16 distinct shades from white to gray.
Adjusting brightness and contrast helps reveal the full range of displayable colors. For example, if you cannot see the subtle EdMar logo in the page background, your monitor may be set too bright or high in contrast.
Proper calibration improves visibility of subtle color differences and ensures the widest range of brightness and color is displayed.
Colors shown on charts are as accurate as possible but not exact. Thread dyes cannot be fully reproduced on screens or printers. Variations in monitors, browsers, settings, dye-lots, thread weight, and lighting conditions all affect perceived color.
