In a model-driven app it is possible to specify for option-sets / choices, colors for the different options. E.g. Color 'Green' for 'Positive' Choice and color 'Red' for 'Negative' Choice.

This color configuration is not displayed for the field / column in the model-driven app.

The documentation also describes how colors can be set for different options in a choice set.

Nevertheless, there is only one color for all options: green regardless of the specified colors in the settings.
