For this task, use the site brandmark.io , which is based on a neural network and trained on a million logos. The service has a number of useful functions:
— Uniqueness check
The site will display the corresponding percentage compared to the service base. In addition, similar logos will be displayed with an indication of their number.
— Legibility Level
The site will display how clear the contours of the logo elements are. This is useful for low resolutions, when viewing the logo from afar and on mobile devices
— Color and Contrast
Determines both the quality of the selection of logo colors and their combination. This is a subjective parameter and you should not be upset if the percentage turned out to be less than expected.
