Evaluation of Strength and Shade

The glare of a dye generally refers to the degree to which the dye strongly reflects or transmits light when it interacts with a light source. The strong light evaluation of the dye can be measured by the following indicators:

• High light reflectance: The dye has a weaker ability to absorb light, so its high light reflectance is higher and the reflected light is brighter.
• Light transmittance: The light transmittance of the dye under the light source can be evaluated by the light transmittance.
• Dispersion: Whether the dye solution can be dispersed into smaller color components under strong light irradiation. If the dispersion performance of the dye is good, it will make the reflected or transmitted light under strong light more uniform.

The color light evaluation of dyes mainly focuses on the color performance of dye solutions or dyed objects under light sources. The shading evaluation of dyes can be measured by the following indicators:

• Hue: The hue of a dye refers to the color it presents under the light source, which can be represented by a color coordinate system (such as RGB, CMYK, etc.).
• Color Saturation: The color saturation of a dye describes the purity and vividness of its color.
• Brightness: The brightness of a dye refers to how light or dark it is under a light source.

To sum up, the strong light evaluation of dyes mainly focuses on the interaction between dyes and light sources, including indicators such as strong light reflectance, light transmittance, and dispersion; while the color light evaluation of dyes focuses on the color performance of dyes under light sources, including Indicators such as hue, color saturation, and brightness.
