Tints apply a single color to an entire group or Symbol. Unlike fills, Tints respect semi-filled elements with different opacities and borders. They’re great for things like complex icons, or tabs in a navigation bar, where you want to show different states through a change in color.
Note: The option to add a Tint is only available when you select a group of layers or a Symbol instance.
How to apply a Tint
To apply a Tint to a group or Symbol instance, click the + icon in the Tint panel in the Inspector. Tints work in a similar way to fills, so you’ll be able us the Color Picker or enter a hex code and change the overall opacity. However, you can only select a solid color to use as a Tint.
In this example, the semi-filled parts of the icon still have take on the Tint color, but with a lower opacity that reflects their original design
How to use Tints as overrides
To use Tints as overrides with nested Symbols, you’ll first need to apply a default Tint to any Symbol instances on the Symbol Source you’re working with.
For example, in the case of a tab bar where each tab is its own nested Symbol, you’ll need to head to the tab bar Symbol Source and apply a Tint to each tab Symbol instance.
Now, when you view your tab bar Symbol instance 
, you’ll see a color icon to the right of each nested Symbol’s name in the Inspector. Clicking on this will bring up the Color Picker so you can override the default Tint for each Symbol.
