Testing `ColorTranslator.FromHtml` with ARGB hex values.

try
{
    // Incrementing by 5 to save time. Using `++` would cover all possible values but takes a long time.
    for (int a = 0; a <= 255; a += 5)
        for (int r = 0; r <= 255; r += 5)
            for (int g = 0; g <= 255; g += 5)
                for (int b = 0; b <= 255; b += 5)
                    ColorTranslator.FromHtml($"#{a.ToString("X2")}{r.ToString("X2")}{g.ToString("X2")}{b.ToString("X2")}");
    Console.WriteLine("All is good!");
}
catch (FormatException ex)
{
    Console.WriteLine($"Failed. Message='{ex.Message}'");
