The paper is perceived to be white due to high clarity, elevated diffusion and minimum perception of hues.
The "color" shade of white paper, which is not to be confused with brightness. Some papers are "blue-white", others tend to be "cream-white".
The intensity of white of a paper stock.
the measure of the amount of light reflected from a sheet of paper. How white a paper is depends on how evenly it reflects all colors in the visible spectrum. If it reflects more blue than red and yellow, it will have a cool, blue tinge to it, making it appear brighter than white. A cool paper will appear brighter than a similar paper with a warm tinge. A cool or warm tinge doesn't affect paper quality, but it does create optical impressions. For example, in color printing with blues and blacks predominating, a cool white sheet tends to brighten the colors. But color printing with reds, oranges, and yellows predominating, a neutral or warm white sheet tends to make the colors appear clearer and stronger. see also brightness, fluorescent dye, refractiveness
The ability to reflect all colors of light equally.
The color white is defined in colorimetric terms as a color with the highest luminosity, no hue and no saturation
A measure of the amount of light reflected from a sheet of paper. Paper that reflects more blue than red or yellow will have a cool, blue tinge and appear to be a brighter white than a warm tinged sheet.
Whiteness of pulp and paper is generally indicated by its brightness, which is the reflectance of a wavelength of blue light. So-called white papers have a definite hue. Most are made with a blue white tint.
The paper’s ability to reflect the entire visible spectrum of light.
A description of both the total ammount and purity of white light reflected from a surface. Often expressed as CIE Lab, where figures are given for total refectance, red-green, and blue-yellow hue.
So-called white papers have a definite hue. Most are made with a blue-white tint. Whiteness of pulp and paper is generally indicated by its brightness which is reflectance of a wave length of blue light.
