Based on your query for “угольный” (which translates to “coal” in English), I have created a dark and moody color palette that reflects the deep, rich tones associated with coal. Here is the color palette:

json
{
  "palette_name": "Coal Essence",
  "colors": [
    {
      "name": "Charcoal Black",
      "hex_code": "
                            
                            #2C2A29
                        "
    },
    {
      "name": "Slate Gray",
      "hex_code": "
                            
                            #4E5452
                        "
    },
    {
      "name": "Ash Gray",
      "hex_code": "
                            
                            #B2B2B2
                        "
    },
    {
      "name": "Coal Dust",
      "hex_code": "
                            
                            #3B3B3B
                        "
    },
    {
      "name": "Burnt Umber",
      "hex_code": "
                            
                            #8B5B29
                        "
    }
  ]
}

This palette features deep black and gray tones, with subtle hints of brown to reflect the earthy aspects of coal.

What kind of project are you planning to use this palette for?
