DMC 400 to J&P Coats: Thread Conversion

J&P Coats 5349 is a close match for DMC 400 Dark Mahogany. It captures the warm, fiery dark brown character adequately for standalone antique wood, leather, and warm shadow applications. For the most demanding uses — shading sequences where 400 must work precisely alongside the darker and lighter mahogany family members across a full gradient — comparing 5349 in context against your other gradient shades in natural light before committing is the right approach to ensure the red-brown warmth reads correctly at each position in the sequence.
