*Gut Morning's logo mark is based on the principle of using full color, but it can be used in a single color depending on the characteristics of the application medium. The ideal color expression of the logo mark is to express it in color on a white background or to apply a white logo on a gradient color background, but it can be flexibly selected depending on the characteristics of the application medium. However, the logo mark should be used in consideration of the brightness contrast with the background color so that it stands out.
