Value Look at this photograph by Jilda Morera. Notice all the shapes, details, and textures and ask yourself what gives them depth or dimension. It is value.
Value describes the range of lightness or darkness of a visual element.
The relationship of the lightness and darkness is value contrast . This allows us to see imaged and perceive detail. We need value contrast in order to read words on a page. If the words on a page were almost the same value as the page, then it would be difficult to read them. Usually text is black and the page is white for the most contrast.
