# Contour Styles Fill Colors

## Content



The [Chart3DContourStyles](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DContourStyles.html) object has two properties that allow for easy manipulation of the contour styles fill color: the [Colors](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DContourStyles.Colors.html) property, and the [ColorSet](/componentone/api/win/online-chart3d/dotnet-framework-api/C1.Win.C1Chart3D.4.8/C1.Win.C1Chart3D.Chart3DContourStyles.ColorSet.html) property. When the ColorSet property is set to **Custom** the fill colors for all contour styles is generated automatically using smooth transitions through colors defined in the **Colors** collection property. When the ColorSet property is set to one of the predefined values (Rainbow, RevRainbow, BlackWhite, WhiteBlack) the fill colors are generated using one of these predefined colors collections.

The following table displays the ColorSet values for Rainbow and BlackWhite in the Surface 3D Chart:
