1. Consistent visual language
Icons with related meaning should keep the primary image content consistent to make them easy to recognize.
Maintain the grid accuracy and do not dismiss safety margin. Since the icons must also work for very small sizes, low resolution of icons must be handled carefully while designing.

Depending on the format, the icons differ in their perceived size. This difference should be considered when designing and should be balanced.
Use the icons in regular style. Black icons are used for active or pressed states. The bold variant is a supplement to the two basic versions. It is used additionally when the two standard versions are not sufficient.
Do’s & Don’ts
