Size
Icons are available in two sizes to accommodate different environments and their requirements: medium and large.



Color
The icon is always solid and monochromatic. The color choice reflects the importance and function of the icon’s action, helping to guide the user.




Alignment
There are two types of icon alignment.
By default, icons are aligned in the geometrical center of the icon grid and its boundary box. This type of centering ensures that all icons are correctly aligned when exported and used side-by-side in a line or a row.
In some cases, you may need to center the icons in relation to their optical center because the geometrical center would break the icon design. This is a spot where visual weight is the heaviest. See the example of the comment icon in the picture below: the pink circle represents the geometrical center, but as you can see, the icon is aligned to its visual center, which is slightly above.
