操作方法：在 ArcGIS Pro 中，应用属性字段中的十六进制或 RGB 颜色代码作为要素符号系统

摘要

In ArcGIS Pro, features in a layer can be symbolized as a single symbol or unique values, or through the graduated colors method. In some instances, the features of a layer must be symbolized based on Hex or RGB color codes from the layer's attribute field so they can be differentiated. This article describes the steps to add Hex or RGB color codes from the attribute field as a feature symbology in ArcGIS Pro.

过程

1. In ArcGIS Pro, open the attribute table of the layer.
2. Click the Add icon to add a new Text data type field. Populate the new field with the desired Hex or RGB color code value.

The image below shows an example of the Hex color codes.

The image below shows an example of the RGB color codes.

3. In the Contents pane, right-click the layer, and click Symbology.
4. In the Symbology pane, click the Vary symbology by attribute icon, and check the Allow symbol property connections check box.

5. Click the Primary symbology icon, and select the symbol next to Symbol.

6. In the Format Polygon Symbol pane, click the Properties tab. After that, click the Layers tab.
7. In the Appearance section, click the Set attribute mapping button next to Color.

8. In the Set Attribute Mapping dialog box, choose the field containing the color codes, and click OK.

9. Click Apply.
