Warm accords often develop through several overlapping effects rather than one dominant smell. Amber materials can provide depth, while vanilla and tonka bean soften the composition. Resinous materials such as myrrh and Peru balsam introduce balsamic richness, and saffron can stop the accord becoming too soft by adding dryness and spice.
Warmth can therefore sit underneath many different fragrance styles. In a floral perfume it may make the flowers feel fuller, while in a woody composition it can soften dry woods. In a gourmand fragrance it can strengthen the sense of comfort without necessarily adding more sugar. A Warm accord describes this combined sensation inside the perfume and should not be confused with Luxaro's Warm & Ambery fragrance family, which classifies the overall finished fragrance.
