A warm, bright, and vibrant color that represents many things to us, yellow is the color of the sun, gold, spirituality, and inspiration. On one hand, we relate yellow to goodness and joy, on the other, cowardice and caution. Would the "happy face" be so happy if it were red instead of yellow? Yellow is the color chosen for yield signs and warning labels (Figure 3). The color of graphic lightning bolts, it suggests energy and electricity. Used in interior design, it brightens up the room that is otherwise dull. Yellow roses are a symbol of friendship, less passionate or threatening than red ones.
