White light is a mixture of all of the colors of the spectrum. White paint is created with pigment, often titanium dioxide. While white light contains all of the frequencies of the optical spectrum, and white pigments reflect all colors of that visible spectrum.
If you are talking about Light then you will get White light. If you are mixing pigments then you will get Black.
Contrast Ratio
A beam of white light is white. A laser is not; it's monochromatic (one specific frequency of light, therefore colored and not white).
Light receptors are found in the eye. There are two types of receptors; rods and cones. Rods produce the black and white pigments and the Cones produce the color pigments.
Darker pigments like black absorb more light/ energy/ heat than lighter pigments like white
White light is a mixture of colours, light from gaseous elements is of one colour, sometimes of just one wavelength (frequency)
Light is available in a variety of wavelengths depending on the emitter. Black light is in the ultraviolet range. White light is a mixture of frequencies in the visible range.
One's white and one's black, just like she said.
Rods are the primary pigments in the retina of eye detecting black and white light or objects.
When some objects get hot enough, they glow, given off a faint red light . If they get even hotter, the glow turns into white light. The objects are said to be white light
White light is a composition of colours. Usually remembered as VIBGYOR. Violet, Inidgo, Blue, Green, Yellow, Orange and Red.
