DMC 300 to Cosmo: Thread Conversion

Cosmo 2513 is close but may lean slightly less red and slightly more neutral brown than the DMC original. In a mahogany gradient where DMC 300 sits alongside 301, 400, and 3776, this slight drift from red-brown toward neutral-brown could disrupt the family's color cohesion. Test Cosmo 2513 in context — not just against DMC 300 alone, but against the other mahogany threads in your palette — before committing it to the darkest shadow position. For standalone uses of this thread where surrounding colors are not mahogany-family, the close match is generally adequate.
