System.Drawing.Color should not be used anywhere in the Uno API set. Aside from that, this is a Xamarin-specific issue.

[Cheesebaron]

System.Drawing.Color is available if you add OpenTK as a Framework Reference.

 <ItemGroup Condition=" $(TargetFramework.StartsWith('xamarin.ios')) ">
    <Reference Include="OpenTK-1.0" />
</ItemGroup>

If Uno,UI or some other library is using System.Drawing.Color, you should probably consider adding this dependency.

Underlying Xamarin issue: xamarin/xamarin-macios#5273

I think we can close this as it's not Uno-related, it doesn't affect the Uno/WinUI API set, and there's not much we can do about it.
