Is there an easy way to blend two System.Drawing.Color values?

Question

Is there an easy way to blend two System.Drawing.Color values? Or do I have to write my own method to take in two colors and combine them?

If I do, how might one go about that?

Answer 1

I wrote a utility method for exactly this purpose. :)

/// <summary>Blends the specified colors together.</summary> /// <param name="color">Color to blend onto the background color.</param> /// <param name="backColor">Color to blend the other color onto.</param> /// <param name="amount">How much of <paramref name="color"/> to keep, /// “on top of” <paramref name="backColor"/>.</param> /// <returns>The blended colors.</returns> public static Color Blend(this Color color, Color backColor, double amount) {     byte r = (byte) (color.R * amount + backColor.R * (1 - amount));     byte g = (byte) (color.G * amount + backColor.G * (1 - amount));     byte b = (byte) (color.B * amount + backColor.B * (1 - amount));     return Color.FromRgb(r, g, b); }
