Repro Screenshot.

Testing Environment:
   OS: 
      •	Windows 10.
      •	Version 1067.
      •	Build 14393.607.
   Visual Studio and Xamarin:
      •	VS 2017 RC Enterprise.
      •	Xamarin For VS 4.3.0.550.
      •	Xamarin Profiler 1.0.4

Pre -Requisites: Build and Deploy Xamarin Application into Android Emulator

Repro:
   Scenario-1:
      1.Launch Xamarin profiler through Visual Studio.
      2.Navigate to "Choose an Instrument Template" window.
      3.Observe the color contrast for the "Arrow mark" in the breadcrumb bar.

   Scenario-2:
      1.Launch Xamarin profiler through Visual Studio.
      2.Navigate to "Choose an Instrument Template" window.
      3.Observe the  color contrast ratio for the "Bullet Points" for selected "Allocations" tab (under Class column) at "Instrument Detail Area" section.
   
   Scenario-3:
      1.Launch Xamarin profiler through Visual Studio.
      2.Navigate to "Xamarin Profiler" window.
      3.Observe the color contrast for "Plus(+)" button above the time span scale.

Actual Result:
   Scenario-1:
      Luminosity contrast ratio is less than 4.5:1 for the "Arrow mark" against the background.

   Scenario-2:
      Luminosity contrast ratio is less than 4.5:1 for "Bullet points" in selected "Allocations" tab against the background.

   Scenario-3:
     Luminosity contrast ratio is less than 4.5:1 for "Plus(+) " button against the background.

Expected Result: 
   Scenario-1:
      Luminosity contrast ratio should be above 4.5:1 for the arrow mark against the background.

   Scenario-2:
      Luminosity contrast ratio should be above 4.5:1 for "Bullet points" in selected "Allocations" tab against the background.

   Scenario-3:
      Luminosity contrast ratio should be above 4.5:1 for "Plus(+) " button against the background.

User Impact:
People with low vision often have difficulty to identify the arrow mark that do not contrast with their background color.
