Sorry for not elaborating on the colors. The picture was downloaded from the internet on primary colors (RGB) which combined forms White color. White color reflects all light and black color absorbs all light. White color is the color created by the combination of the primary colors of Red, Green and Blue in suitable proportions. I was surprised that the horses in Revelation 6 mentioned all those colors of white, red, black, green/yellow except blue, not sure why but I do know that green is a mixture of yellow and blue, yellow is a mixture of red and green.

Pigments that absorb light rather than reflect it back to the eye "look black". A black pigment can, however, result from a combination of several pigments that collectively absorb all colors. If appropriate proportions of three primary pigments are mixed, the result reflects so little light as to be called "black".
This provides two superficially opposite but actually complementary descriptions of black. Black is the lack of all colors of light, or an exhaustive combination of multiple colors of pigment.
In physics, a black body is a perfect absorber of light,
See wiki on White color:
White light is the effect of combining the visible colors of light in suitable proportions (the same present in solar light).
Since the impression of white is obtained by three summations of light intensity across the visible spectrum, the number of combinations of light wavelengths that produce the sensation of white is practically infinite. There are a number of different white light sources such as the midday sun, incandescent lamps, fluorescent lamps and white LEDs; due to the phenomenon of metamerism, such sources can appear similar whilst having quite different spectra. The impression of white light can also be created by mixing appropriate intensities of the primary colors of light, red, green and blue (RGB), a process called additive mixing, as seen in many display technologies.
See wiki on Red color:
Red is any of a number of similar colors evoked by light consisting predominantly of the longest wavelengths of light discernible by the human eye, in the wavelength range of roughly 630–740 nm.
See wiki on Green color:
Green is a color, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of roughly 520–570 nanometres. In the subtractive color system, it is not a primary color, but is created out of a mixture of yellow and blue, or yellow and cyan; it is considered one of the additive primary colors.
See wiki on Yellow color:
Yellow is the color evoked by light that stimulates both the L and M (long and medium wavelength) cone cells of the retina about equally, with no significant stimulation of the S (short-wavelength) cone cells. Light with a wavelength of 570–580 nm is yellow, as is light with a suitable mixture of red and green.

Ask and You shall receive,
