Testing `ColorTranslator.FromHtml` with ARGB hex values.

            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!");
