Carrefour Supermarket is a famous large-scale supermarket chain in France. Its name is derived from the word crossroads, which explains the red and blue arrows pointing in opposite directions on the logo. The white area on the logo is also cleverly used. If you look closely, you can find that it is actually the letter C.

This capital letter C is set against the red and blue colors of the French flag. The upper and lower edges of the letter C are greatly expanded, making it blend into the background. This is the most ingenious move by a designer and the most successful part of the design. At the same time, it also leads many people who do not pay attention to trademarks into misunderstandings, causing people to see fragmented images and color blocks.
