Color FeatureLayer by dynamic RGB or HEX attribute values

RyanVeenstraGHD

I am trying to render a large dataset of points or polygons, and colour them directly based on hex or RGB values that exist directly in the attributes of each feature.

I do not want to use a UniqueValueRenderer to manually define stops, etc.  I just want to send the RGB value from the attributes directly into the renderer for that point/polygon.  This is very simple to do with Mapbox, but seemingly not simple with the ArcGIS Javascript API?

My very simple renderer - I just want color to directly use the HEX in the attributes of each feature.

renderer: {
  type: "simple",
  symbol: {
    type: "simple-fill",
    color: <make-me-attribute-driven>,
    outline: null
  },
}

 

Note: I can do this manually by using a GraphicsLayer and creating each graphic individually where I define it's colour etc, however I want to take advantage of Clustering and some of the other FeatureLayer capabilities not available to GraphicsLayers.

Is this actually possible?  All the examples use UniqueValueRenderer to colour based on a defined number of stops, which is not what I want.

Ah, ok. this is something that can be done via CIMSymbol and primitive overrides. Here's a sample.

primitiveOverrides: [
    {
        type: "CIMPrimitiveOverride",
        primitiveName: "colorOverride",
        propertyName: "Color",
        valueExpressionInfo: {
        type: "CIMExpressionInfo",
        title: "Arcade color override",
        expression: `
            // return "rgb(0,255,0)"
            return $feature.NAIP_rgb;
        `,
        returnType: "Default"
        }
    }
]
