While there's no single definitive answer, research suggests that red may be associated with improved memory performance.
- Studies have shown that memory for red-colored objects is higher than for blue and green objects. (Source: Differential binding of colors to objects in memory: red ... - Frontiers)
- Red has been linked to boosting memory performance in several studies, along with blue. (Source: Memory Enhancement: Your Brain on Color)
- Warm colors like red, yellow, and orange have been found to have a greater effect on attention and potentially memory. (Source: The Influence of Colour on Memory Performance: A Review)
It's important to note that the relationship between color and memory is complex and not fully understood. Other factors like individual preferences, context, and learning methods can also influence memory.
