Crash when accessing PlatformColor('Complement')

[chrisglein]

Problem Description

This is when using one of the defined accent color constants from the PlatformColor implementation, specifically Complement

Of note... looks like all the other values defined in that set work fine. So maybe Complement should just be removed?

  auto uiColor = s_uiColorTypes.find(platformColor);
  if (uiColor != s_uiColorTypes.end()) {
    auto uiSettings{winrt::Windows::UI::ViewManagement::UISettings()};
    color = uiSettings.GetColorValue(uiColor->second); // <--- HERE
    auto pair = std::make_pair(true, color);
    m_colorCache[platformColor] = pair;
    return true;
  }

Steps To Reproduce

PlatformColor('Complement')

Expected Results

PlatformColor with a bad constant should not crash (in Paper it resolves to transparent). PlatformColor actually has a fallback mechanism where you pass in an array of options. At most I'd expect a log / yellow box (although we didn't do that on Paper).
