So a designer can use warm colors for emphasis and cool colors to minimize emphasis. Brighter colors attract our eyes first, and if overused, can cause visual confusion. Overusing a bright color as an accent reduces its effectiveness. Emotional responses influence color considerations, and differences in color value and intensity can evoke very different emotional reactions.
Light red is associated with cheerfulness, but bright or dark red can induce irritability.
Light yellow-green is associated with freshness and youth, but the darker shade olive is associated with drabness and decay. Light sky blue is associated with tranquility, but the deeper value indigo is associated with depression. This emphasizes the importance of careful color selection and coordination. Different cultures interpret colors differently, and a savvy Web designer can avoid disappointing results and costly re-works by some upfront cultural research. White is the color of death in Chinese culture, but purple represents death in Brazil.
