FTLOG Don't use light gray on a white background

Start by examining how the PowerShell ISE theme maps the keyword.operator scope and compare it with the reported editor.tokenColorCustomizations workaround. Use the provided PowerShell sample to check the contrast of -, =, !, $, and @; done means these syntax elements are readable on the white background without custom user settings.

Environment

• VS Code 1.41.1
• Your primary theme: "PowerShell ISE"

Issue Description

Insufficient contrast between = ! - , and the background, and exacerbated when the use has render white space on.

Screenshots

Notice the last line has a misplaced - sign which is very hard to see. Params is rendered here as the name of a variable which will be splatted, but -@params is treated as a string literal to be passed as a parameter value .
In the ISE the - sign changes the rendering

Supplementary In the ISE, the $ and @ are rendered in the same colour as the variable name.

Expected Behavior

I am now working around this by adding the following to my vs code settings

    "editor.tokenColorCustomizations": {
        "[PowerShell ISE]": {"textMateRules": [
            {
                "scope": "keyword.operator",
                "settings": {
                    "foreground": "#000000",
                }

            }
        ]}
    },

Code Samples

    $Params.Uri      = "$repoUri/annotatedtags?api-version=5.1-preview" 
    $Params['Body']  = [ordered]@{
        name         = $Name
        taggedObject = @{objectId = $env:BUILD_SOURCEVERSION} 
        message      = $Message } | ConvertTo-Json -Depth 2
    Invoke-RestMethod   -@Params   -ContentType 'application/json' -Method Post  | Format-List

Suggestion

Maintain a difference of at least 127 (50%) between the background and syntax elements. The rgb values for these elements are A9A9A9 (169 decimal), which is the 2/3 point rather than the 50%

Consider using smaller even differentials between rendered white space/control characters and the back ground or
