C#で色指定の際にDarkRedなど名前で指定ができますが、これらが何色なのかどんなカラーコードなのか、ほかにどんな色があるのかと思うことが多々あるので列挙してみます。
public static void Test1()
{
var colors = Enum.GetValues(typeof(KnownColor))
.OfType<KnownColor>()
.Select(c => Color.FromKnownColor(c));
foreach (Color color in colors)
{
Console.WriteLine($"{color.R},{color.G},{color.B} : {color.Name}");
}
}
下記のように出力されます。
