如何在C#中使用两种颜色之间的RGB差，以便找到最接近的匹配？

struct Color
{
    public int Red;
    public int Green;
    public int Blue;
}

double CalculateColorDifference(Color color1, Color color2)
{
    int redDiff = color1.Red - color2.Red;
    int greenDiff = color1.Green - color2.Green;
    int blueDiff = color1.Blue - color2.Blue;

    return Math.Sqrt(redDiff * redDiff + greenDiff * greenDiff + blueDiff * blueDiff);
}

Color FindClosestColor(Color targetColor, List<Color> colorList)
{
    Color closestColor = colorList[0];
    double minDifference = CalculateColorDifference(targetColor, closestColor);

    foreach (Color color in colorList)
    {
        double difference = CalculateColorDifference(targetColor, color);
        if (difference < minDifference)
        {
            minDifference = difference;
            closestColor = color;
        }
    }

    return closestColor;
}

Color targetColor = new Color { Red = 100, Green = 50, Blue = 200 };
List<Color> colorList = new List<Color>
{
    new Color { Red = 255, Green = 0, Blue = 0 },
    new Color { Red = 0, Green = 255, Blue = 0 },
    new Color { Red = 0, Green = 0, Blue = 255 }
};

Color closestColor = FindClosestColor(targetColor, colorList);
Console.WriteLine($"Closest color: R={closestColor.Red}, G={closestColor.Green}, B={closestColor.Blue}");
