# 6. ZonesMap: custom color schema

Field-related data layers are located in the `field` -> `vectorAnalysisMaps` -> `geoMaps` attribute. It has the origin and thumbnail "VectorAnalysisMap" representations. Every `geoMap` contains complete details about the access `url`, color codes, classes, and view names.

{% hint style="info" %}
As the first option, the new color schema can be applied directly via the following sample `env=c1:%23762a83%3Bc2:%23af8dc3%3Bc3:%23e7d4e8%3Bc4:%23d9f0d3%3Bc5:%237fbf7b` should be checked, where `%23` is `#` symbol and `%3b` is `;` symbol.
{% endhint %}

As the second option, the new color can be saved in advance via[ Mutation: Set custom color schemas to selected "GeoMaps" mutation](https://docs.geopard.tech/geopard-tutorials/api-docs/requests-overview/39.-mutation-set-custom-color-schemas-to-selected-geomaps).
