How to create a POJO for the following json?

I want to map following json to a pojo using jackson.

{
  "colors": {
    "red": {
      "colorCode": "#FF0000"
    },
    "green": {
      "colorCode": "#00FF00"
    },
    "blue": {
      "colorCode": "#0000FF"
    }
  }
}

Is there any possible way to create a single POJO without having to create POJOs for each color because every color contains same parameter(colorCode)?

Note: I tried using @jsonAlias but it wont work because it overwrites that parameter.

The name of the color is just the name. Unless blue Behaves differently then Red, then they should not be separate classes.

Public class Color{
Private string colorCode;
Private string title

Color(string colorCode, string title){
This.colorCode =colorCode;
This.title = title;
}

Getter setters etc

The simplest solution would be to use a Map < String, Color > (or maybe Enum if you have a fixed list of colors)

public class Color{
  private String colorCode;

  //constructor, getter, setter
} 
public class Pojo{
   private Map<String,Color> colors;

  //constructor, getter, setter
}
