The phrase "bright colors" refers to vivid, bold and lively shades that stand out due to their high visibility. These are typically cheerful hues such as reds, yellows, oranges, pinks, blues, greens, purples, and many others that grab attention easily because of the intensity of light they reflect. Bright colors can be used in fashion, artwork, interior design, and other creative expressions to convey energy, happiness, excitement, and positivity.
