Issue Description

Certain (perhaps overzealous) antivirus software flags the line

[Reflection.Assembly]::LoadWithPartialName('System.Drawing') > $null

as malicious, because "reflective code loading" can be used to execute a payload while avoiding some forms of malware detection.

I was able to work around this for myself by removing this line and replacing references to the $ColorType and $ColorTranslator variables with [System.Drawing.Color] and [System.Drawing.ColorTranslator]. See commit ed72492 in my fork. However, this solution fails 18 tests with messages like Unable to find type [System.Drawing.Color], presumably because the System.Drawing assembly is not part of .NET Core/5/6 except via NuGet packages.

It would be nice to get something like this upstreamed, so that I can install future updates without having to modify them. I am not sure whether it is possible (or desirable) to have a NuGet dependency that would allow this to work, or whether there might be another solution that would work better.
