Things change and one thing you can almost count on these days is that red threads will change. New environmental laws seem to affect red more than any other color. This means reds are less colorfast and that the same color number may be a different color.
Thanks to the South Bay Chapter (San Jose) for providing this information.
European laws have caused DMC to change their formulas, affecting several colors of red. The affected colors are: 304, 321, 498, 815, and 816. You can tell if the skein you have is new or old by looking at the tag with the number. The new formulas have a dot after the number.
This affects us in North America because DMC is an imported thread and follows European laws about dyes, not US or Canadian ones.
There are suggested substitutions for several DMC colors that have been discontinued. These colors are discontinued because they are very similar to other DMC colors.
These substitute numbers are now double numbered with the color number large and the discontinued number showing small on the label.
