Using black as the background color of a quiz is ugly because it is difficult to read the text and it makes the quiz look unprofessional.

Black is a very dark color, and it can be difficult to read text on a black background. This is especially true if the text is not very bright or if the font is small. Additionally, black can make a quiz look very dull and uninteresting. A quiz with a black background is not likely to engage or excite the user.

There are many better colors to use for the background of a quiz. Some good options include light gray, white, or a light pastel color. These colors are easier to read and they make the quiz look more inviting. Additionally, you can use a contrasting color for the text, such as white text on a black background or black text on a light gray background. This will make the text easier to read.
