Step-by-step explanation:
The most important thing to remember about contrast on web pages is to create a balance between the colors used. Contrast refers to the difference in colors used to create visual impact. It is important to find the right balance between too much contrast, which can be overwhelming, and too little contrast, which can make it difficult for the reader to perceive the information. For example, using black and white as a stark contrast can bring vitality to a web page, while using monochromatic colors can create subtle contrast and add variety and unity.
