When your geographic processing service outputs a grid, you need to add different colors for each type of grid data, and the grid color is random by default, or a fixed set of coloring solutions is not user-friendly enough to meet diverse customer needs. Let's talk about how to solve this grid dynamic color problem.
The first thing you need to do is to implement the grid color scheme on ArcMap,
Right-click the grid, select Properties, symbol system labels, and color ing table.
Click the triangle in the lower-left color ing table, and select export color ing table, named *. CLR.
After creating a color ing table, you can create a dynamic color model.
Add a color ing table using data management tools grid and grid Properties
Set *. CLR as a model parameter. After publishing as a service, you can select your preferred color scheme and set the output Grille To display. The entire scheme process is over.
