are compared (such as price, size or quality) and, in the case of "better," what the product is compared to (a competitor's product, an earlier version of their product, or nothing at all). Without defining the terms "better" and "best", they become meaningless. An ad that says, "Our cold medicine is better" could be claiming that it is an improvement over taking nothing at all. Another often-seen example is "better than the leading brand", with a statistic attached; the "leading brand", however, is undefined. Inconsistent comparison In an inconsistent comparison, an item is compared with others only in terms of favorable attributes; this conveys the false impression that it is the best of all products overall. One variant is a website which lists competitors whose price for a particular item is higher, ignoring competitors whose price is lower. Misleading illustrations A common example is the serving suggestion pictures on food-product boxes, which include ingredients other than those included in the package. The "serving suggestion" disclaimer is a legal requirement for an illustration including items not included in the purchase, but if a customer fails to notice (or understand) the caption they may assume that all depicted items are included. Some advertised photos of hamburgers convey the impression that the food is larger than it really is, and foods are "styled" to appear unrealistically appetizing. Products sold unassembled or unfinished may have a picture of the finished product, without a picture of what the customer is actually buying. Video-game commercials may include what are essentially short CGI films, with considerably better graphics than the actual game. False coloring Consumers may buy an item based on the color they saw in an advertisement. When used to make people think food is riper, fresher, healthier, or otherwise more desirable than it really is, food coloring may be deceptive. When combined with added sugar or corn syrup, bright colors convey a subconscious impression of healthy, ripe fruit, full of antioxidants and phytochemicals. One variation is packaging which obscures the color of the foods within, such as red mesh bags holding yellow oranges or grapefruit which then appear to be a ripe orange or red. Regularly stirring minced meat on sale at a deli can make the surface meat remain red (and appearing fresh) when it would oxidize (and brown), showing its true age if left unstirred. Some sodas are sold in colored bottles when
