Limited color range if color field type is temporal

[stas-sl]

Hello, I'm quite new to vega, so not sure if I'm doing it right, but I'm trying to assign colors according to date column, however I get pretty limited color range, as you can see in the first image. Then I changed color field to color2 with type quantitative and got full range of colors as expected, so what's wrong with temporal scale? Can I get same color range with it?

{
  "$schema": "https://vega.github.io/schema/vega-lite/v5.json",
  "data": {
    "values": [
      {"color": "2022-01-01", "color2": 1, "y": 1},
      {"color": "2022-01-02", "color2": 2, "y": 1},
      {"color": "2022-01-03", "color2": 3, "y": 1}
    ]
  },
  "mark": "bar",
  "encoding": {
    "y": {"aggregate": "sum", "field": "y"},
    "color": {
      "field": "color", 
      "type": "temporal",
      "scale": {"scheme": "turbo"}
    }
  }
}

As a workaround I converted dates to timestamps (integers) and used scale quantitative, but this required manual ticks calculation for color legend, so not sure if this solution was optimal.
