If you mean the ASCII logo, you can give its rows different colors. Setting the built-in Debian logo's two colors to blue and white won't automatically blend between them — the colors only replace the $1, $2, etc. markers in the artwork.

Here's a small Debian example with ocean blue at the top and white at the bottom. Save it as a separate gradient.jsonc file so you can try it without replacing your existing config:

{
  "logo": {
    "type": "data",
    "source": "$1  _____\n$2 /  __ \\\n$3|  /    |\n$4|  \\___-\n$5-_\n$6  --_",
    "color": {
      "1": "38;2;0;119;190",
      "2": "38;2;51;146;203",
      "3": "38;2;102;173;216",
      "4": "38;2;153;201;229",
      "5": "38;2;204;228;242",
      "6": "38;2;255;255;255"
    }
  }
}

Then run:

fastfetch --config gradient.jsonc

This is a six-step vertical fade, not automatic interpolation. Each $1–$6 selects that row's RGB color. It needs a terminal with true-color support. I checked this config with Fastfetch 2.69.0 on macOS, rather than Debian.

If you like it, copy just the logo object into your existing config, leaving your modules in place. The same approach works with larger custom ASCII art using up to nine color slots. For more shades, a custom ANSI-colored text file with "type": "file-raw" avoids that nine-slot limit.

The wiki covers logo color markers and custom logos and the RGB color format.
