## SetTwoColorGradient(Color, Color, GradientStyleType, int) {#settwocolorgradient_1}

Sets the specified fill to a two-color gradient. Only applies for Excel 2007.

```csharp
public void SetTwoColorGradient(Color color1, Color color2, GradientStyleType style, int variant)
```

| Parameter | Type | Description |
| --- | --- | --- |
| color1 | Color | One gradient color. |
| color2 | Color | Two gradient color. |
| style | GradientStyleType | Gradient shading style. |
| variant | Int32 | The gradient variant. Can be a value from 1 through 4, corresponding to one of the four variants on the Gradient tab in the Fill Effects dialog box. If style is GradientStyle.FromCenter, the Variant argument can only be 1 or 2. |
