What is Fluorescent Color?
Fluorescent colors are strikingly bright and bold because they absorb and reflect more light than conventional colors. This enhanced light reflection makes them appear significantly brighter and more vibrant. Sometimes, fluorescent colors are also referred to as neon colors. Their unique brilliance stems from their ability to absorb ultraviolet (UV) radiation, invisible to the human eye, and then re-emit this energy as visible light. This process makes them appear to glow, especially under a blacklight.
- Absorption and Re-emission: Fluorescent pigments absorb light energy, including UV light, and then re-emit that energy as visible light. This is different from regular colors, which simply reflect a portion of the light they receive.
- Wider Spectrum Absorption: Fluorescent colors use a larger amount of both the visible spectrum and the lower wavelengths (like UV) compared to conventional colors.
- Increased Brightness: DayGlo Color Corp, a leading manufacturer of fluorescent colors, claims their neon colors are up to three times brighter than conventional colors.
- Visible Light Emission: The emitted visible light determines the color we see. The brightness is a result of the efficient conversion of absorbed energy into visible light.
Examples and Applications:
Fluorescent colors are found in various applications, including:
- Paints and Coatings: Used in art, signage, and decorative applications.
- Plastics: Often used in toys, clothing, and other consumer products.
- Graphic Arts: Creating eye-catching designs in printing and advertising.
- Security Applications: Invisible fluorescent pigments are used for anti-counterfeiting measures.
Understanding the Difference:
The key difference between fluorescent and conventional colors lies in their interaction with light. Conventional colors simply reflect existing light, while fluorescent colors absorb energy and re-emit it as brighter, more intense light. This explains their intense vibrancy and apparent glow.
