Are black & white colours or shades of colour?

Well, pure white is the absence of color because you cannot create white with a mix of colors. Also I know that red, yellow, and blue combined will create a type of black.

The color of light is determined by its wavelength. Red has the longest wavelength, continuing through the colors of the rainbow (ROY G BIV). This is a continuous spectrum with no real distinctions between any given shades.

Light that appears white to us is an even mixture of all the wavelengths. 'Black' simply is an absence of any light at all. In the attached picture, you can see how monitors and other things create a fair approximation of the full spectrum of colors by mixing red, green, and blue together in various amounts.

LeisureLife's response is on the right track but somewhat backwards. It can seem this way when dealing with paints because of the way they work. As opposed to monitors which create light, pigments and dyes work by absorbing it.

For example, yellow paint looks yellow because it absorbs everything but the yellow wavelengths (which it reflects back out) from the full spectrum of white light in the room. So, combining red, yellow, and blue paint in his example will overlap and end up absorbing some of every wavelength. This again gives an absence of light which appears black.

Actually, Physics tells us that black and white a blends of many colors.

Shades of black are colors that differ only slightly from pure black. These colors have a low lightness. From photometric point of view, a color which differ slightly from black always has low relative luminance.

Variations of black include what are commonly termed off-black colors, which may be considered part of a neutral color scheme, usually in interior design as a part of a background for brighter colors. Black and dark gray colors are powerful accent colors that suggest weight, dignity, formality, and solemnity. In color theory, a shade is a pure color mixed with black.

It decreases its lightness while nearly conserving its chromaticity. Strictly speaking, a “shade of black” is always a pure black itself and a “tint of black” would be a neutral gray. Unlike these, many off-black colors possess a hue and a colorfulness (also called saturation).

Colors often considered "shades of black"—even if they are not technically shades—include onyx, black olive, charcoal, and jet; these colors and other variations of black are shown below. Black is a color, the perception of which is evoked by the total absence of light that stimulates any of the three types of color sensitive cone cells in the human eye and with very low brightness compared to the surroundings. A black visual stimulation will be void of hue and grayness.

Black is the darkest possible color. The colors are arranged in order of value (brightness) (v code in the hsv code), the lightest colors at the top and the darkest at the bottom. Midnight blue is a dark shade of blue named for its resemblance to the identifiably blue color of a moonlit night sky on or near the night of a full moon.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
