Tints apply a single color to an entire frame, graphic, group or Symbol. Unlike fills, Tints take into account semi-filled elements with different opacities and borders. Tints are great for things like complex icons or tabs in a navigation bar — or anywhere you want to show different states through a change in color.
Applying a tint
To apply a Tint, select a frame, graphic, group or Symbol instance then click on the Effects section header, or + icon and select Tint. Tints work in a similar way to fills, where you can use the Color Picker or enter a hex code and change the overall opacity. However, you can only select a solid color as a tint.
Semi-filled parts of this sample icon take on the Tint color, but with a lower opacity that reflects the original design
Using tints as overrides
To use tints as overrides with nested Symbols, you first need to apply a default tint to any Symbol instances on the Symbol Source you’re working with.
Now, when you select a Symbol instance 
, you’ll see the tint override as a color override in the Color section in the Inspector. Clicking on the color icon will bring up the Color panel so you can easily override the default tint.
