# 39. Mutation: Set custom color schemas to selected "GeoMaps"

Set custom color schemas to data layers: "ZonesMaps", "SoilDatasets". 

Support for other data layers ("YieldDataset", "TopographyMaps", "SatelliteImages") is coming.

Update all attributes of the "GeoMap":

{% code overflow="wrap" lineNumbers="true" %}

```graphql
mutation UpdateGeoMaps {
  setGeoMaps(input: {
    geoMaps: [{
      fieldUuid: "<placeholder_of_field_uuid>",
      soilDatasetUuid: "<placeholder_of_soildataset_uuid>",
      shortName: "<origin_geomap_short_name>",
      classes: [

        ],
      description: "<some_text_about_geomap>",
      fullName: "<geomap_full_name>",
      hexColorCodes: [
        "#ca0020",
        "#f4a582",
        "#f7f7f7",
        "#92c5de",
        "#0571b0"
      ]    
    }, {

      hexColorCodes: [

      ]    
    }]
  }) {
    shortName
    fullName
    description
    classes
    hexColorCodes
    url
  }
}
```

{% endcode %}

Update only color schemas of the "GeoMap":

{% code overflow="wrap" lineNumbers="true" %}

```graphql
mutation UpdateGeoMaps {
  setGeoMaps(input: {
    geoMaps: [{
      fieldUuid: "<placeholder_of_field_uuid>",
      soilDatasetUuid: "<placeholder_of_soildataset_uuid>",
      shortName: "<origin_geomap_short_name>",
      classes: [
          -6.5,
          100,
          162.60000610351562,
          245.8000030517578,
          493.29998779296875
        ],
      hexColorCodes: [
        "#ca0020",
        "#f4a582",
        "#f7f7f7",
        "#92c5de",
        "#0571b0"
      ]    
    }, {
      fieldUuid: "<placeholder_of_field_uuid>",
      vectorAnalysisMapUuid: "<placeholder_of_vectoranalysismap_uuid>",
      shortName: "<origin_geomap_short_name>",
      hexColorCodes: [
        "#b2182b",
        "#ef8a62",
        "#fddbc7",
        "#f7f7f7",
        "#d1e5f0",
        "#67a9cf",
        "#2166ac"
      ]    
    }]
  }) {
    shortName
    fullName
    description
    classes
    hexColorCodes
    url
  }
}
```

{% endcode %}

**IMPORTANT** points to learn how to use the mutation:

1. Attributes `fieldUuid`, `soilDatasetUuid`/`vectorAnalysisMapUuid`, and `shortName` are mandatory to identify the correct "GeoMap" to amend. All these three attributes together reflect the uniqueness of "GeoMap".
2. Either `soilDatasetUuid` or `vectorAnalysisMapUuid` attribute must be used per single "GeoMap" input.
3. Value of `shortName` must be the same as the origin in the "GeoMap". It is not editable.
4. Attributes `fullName`, `description`, `hexColorCodes` are editable for "ZonesMaps" and can be amended. The changes are not applied if the attribute is not mentioned.
5. Attributes `fullName`, `description`, `classes`, `hexColorCodes` are editable for "SoilDatasets" and can be amended. The changes are not applied if the attribute is not mentioned.
6. Arrays `classes` and `hexColorCodes`  must have exactly the same length as the origin in "GeoMap".
7. The length of "GeoMaps" arrays in the request and the response must be the same. If not, some "GeoMaps" were not edited successfully.
