How to set default values in the "SET"->"TETX" and "COLOR" field

I create a “SET” field and give it options, but the “default” option is ignored when I fill it in. How can I specify the default values?

{
  "fields": [
    {
      "name": "Фон",
      "type": "text",
      "default": "#333333"
    },
    {
      "name": "Название",
      "type": "color",
      "default": "#333333"
    },
  ]
}

Default for field type SET is set under the options key.

Default for field type COLOR is set via the spectrum.js parameters ( Spectrum - The No Hassle jQuery Colorpicker )

{
  "fields": [
    {
      "name": "Фон",
      "type": "text",
      "options": {
        "default": "#333333",
      }      
    },
    {
      "name": "Название",
      "type": "color",
      "options": {
        "spectrum": {
          "color": "#333333"
        }
      }      
    },
  ]
}
