Monochrome photography is often associated with black and white photography, but in fact it is not limited to these shades. As its name implies, a monochrome involves the use in the image of tones and variations of only one particular color from the entire spectrum of colors. Why use monochromatic color?
For a monochromatic color, shades are the result of combining the same color with a different amount of white (English term tint) or black (English term shade). Both color and lack of color are effective ways of conveying emotions. You choose what to use, and your choice depends on the story you want to tell. In particular, you may prefer black and white images for more dramatic or even darker scenes and thus convey more intense emotions. One single color used in your photo can evoke or enhance a variety of feelings. For example, red color is often used to denote passion, love and even anger, while blue causes a feeling of cold, calm, restraint of emotions.
It should be noted that different tones and shades of tone / color also change the intended emotion or its intensity, so we take into account such a thing as the “feeling” of color. You can quote the words of the famous photo-documentary Don Mackalin: “Photography for me is not a vision, but a feeling. If you can’t feel what you are looking at, you can never make others feel anything when looking at your pictures.”
