A successful advertisement must have colors that draw the human eye. The eye is attracted to yellow, so using yellow would be a smart move when creating an ad. An advertisement also has to be fairly simple. The advertisement must be able to express the point easily. It cannot be crowded and confusing. The text of an advertisement cannot be overbearing as well. The colors of the text must also correspond with the color theme of an ad. The ad also has to be appropriate for the age you are trying to reach. If you are advertising a toy, you shouldn't use big & complicated words or put it in a location that doesn't fit.  There shouldn't be an overbearing amount of text or colors that hurt the eye.
