In PowerShell 5 the ConvertFrom-StringData cmdlet does not have a Delimiter parameter and always uses the equals sign (=) as separator between the name and value of the input.

Also, ConvertFrom-StringData always returns a Hashtable, which is unordered by default.

$txt = Get-Content -Path 'TheFile.txt' -Raw
[PsCustomObject]@{'colors-20220906' = ($txt -replace ':', '=' | ConvertFrom-StringData )} | ConvertTo-Json

results in

{
    "colors-20220906":  {
                            "blue":  "2",
                            "yellow":  "3",
                            "orange":  "1"
                        }
}

If the order of subitems is important to you, you need to split the key:value lines yourself:

$txt  = Get-Content -Path 'TheFile.txt'
# create an ordered Hash to retain the order in which the items appear
$hash = [ordered]@{}  
foreach ($line in $txt) {
    $name,$value = ($line -split ':', 2).Trim()
    $hash[$name] = $value
}

[PsCustomObject]@{'colors-20220906' = $hash} | ConvertTo-Json

results in

{
    "colors-20220906":  {
                            "orange":  "1",
                            "blue":  "2",
                            "yellow":  "3"
                        }
}

P.S. PowerShell creates valid JSON, but the format is quite ugly. If you want to prettify that, you can use the function I posted earlier Format-Json
