The contrast of white and black (light and darkness, day and night) has a long tradition of metaphorical usage. Day, light, and sound are often linked together in opposition to night, dark, and evil.
Black is the absence of light. Unlike white and other hues, pure black can exist in nature without any light. Some consider white to be color because white light comprises all the visible light spectrum hues. But technically, black and white are not colors; they’re shades.
If we can think of something, it exists in our thoughts, but if we can capture the black and white in a picture, then it may only represent our thoughts?
Removing the natural color of the flower and replacing it with black and white suggests that it is intended to be taken as a metaphor, something used symbolically to represent something else, offering a comparison or resemblance.
In this picture, it is clear that the image's subject is a flower, but the concept of the flower becomes imaginary, spiritual, or otherworldly, which may be the intent. For some, this might suggest that art informs because it is only revealed,d and if that is the case, then this picture of the flower is art showing itself.
A metaphor in the arts is a visual image meant to be understood by the viewer as a symbol for something else.
Rather than signifying death and mourning, a black rose breaks this more common assumption for black. Its radical difference from the red rose implies a more positive meaning of new beginnings, which, along with indicating significant changes, are common meanings for black roses.
