Generic operators

ColorOperator.cs

        public static Color<T> operator +(Color<T> left, Color<T> right)
        {
            if (typeof(T) == typeof(byte))
            {
                return (Color<T>)(object)new Color<byte>(
                 (byte)((byte)(object)left.R + (byte)(object)right.R),
                 (byte)((byte)(object)left.G + (byte)(object)right.G),
                 (byte)((byte)(object)left.B + (byte)(object)right.B),
                 (byte)((byte)(object)left.A + (byte)(object)right.A));
            }
            
            // etc
        }

Double cast is required due to C# widening when adding to bytes.
