## Animating the Tint on a Grayscale Symbol Lets say you have chosen one of the many grayscale symbols, such as the **3-D Valve** symbol from the **Valves** category, and you want to tint the valve green when the valve is open, red when the valve has a fault, and keep it gray when the valve is closed. Suppose you have a tag called **ValveStatus**, that is 0 for closed, 1 for open, and 2 for faulted. 1. Drag the symbol onto the screen. 2. Duplicate the symbol by selecting it and choosing **Duplicate** from the **Edit** menu, or pressing **CTRL-D**. 3. Now, select the duplicate symbol, which will be above the original. 4. Press the Union button (![union button icon](union-button-icon.png)) in the toolbar or find the **Union** item under the **Shape** menu. This will flatten the duplicated shape into a single shape. ![animate grayscale tint step 4](animate-grayscale-tint-step-4.png) 5. Remove the outline by setting the **Stroke Paint** property to **No Paint**. 6. Bind the **Fill Paint** property to your **ValveStatus** Tag. 7. Add three entries into the number-to-color translation table: * 0% opaque white for 0 * 40% opaque green for 1 * 40% opaque red for 2 ![animate grayscale tint step 7](animate-grayscale-tint-step-7.png) In summary, what we did to tint the symbol was to make a flat shape that had the exact same outline as the symbol, and used semi-transparent fills to achieve a tint effect for the underlying symbol. ![tint SVG result](tint-svg-result.png)
