How to atomically update one array item's property=true and all other array items' property=false

Working with Data

I think I’m going to change my data model to avoid the problem. Luckily I have the luxury to change it. A more convenient data model will look like:

{
  id: "docId",
  colorsDefault: "red",
  colors: [
    {value: "red"},
    {value: "white"},
    {value: "blue"}
  ]
}

Now the update command is obvious. I just need to change a single field and no array elements.

{
  $set: {colorsDefault: "blue"}
}

Still, I wonder if it is possible to remove the property default=true from one array element while atomically updating another element.
