W klasie Color masz takie ... fabryki ??? się to nazywa?
(chyba, ze nie rozumiem pytania)
//
// Summary:
// Creates a System.Drawing.Color structure from the specified 8-bit color values
// (red, green, and blue). The alpha value is implicitly 255 (fully opaque). Although
// this method allows a 32-bit value to be passed for each color component, the
// value of each component is limited to 8 bits.
//
// Parameters:
// red:
// The red component value for the new System.Drawing.Color. Valid values are 0
// through 255.
//
// green:
// The green component value for the new System.Drawing.Color. Valid values are
// 0 through 255.
//
// blue:
// The blue component value for the new System.Drawing.Color. Valid values are 0
// through 255.
//
// Returns:
// The System.Drawing.Color that this method creates.
//
// Exceptions:
// T:System.ArgumentException:
// red, green, or blue is less than 0 or greater than 255.
public static Color FromArgb(int red, int green, int blue);
//
// Summary:
// Creates a System.Drawing.Color structure from the specified System.Drawing.Color
// structure, but with the new specified alpha value. Although this method allows
// a 32-bit value to be passed for the alpha value, the value is limited to 8 bits.
//
// Parameters:
// alpha:
// The alpha value for the new System.Drawing.Color. Valid values are 0 through
// 255.
//
// baseColor:
// The System.Drawing.Color from which to create the new System.Drawing.Color.
//
// Returns:
// The System.Drawing.Color that this method creates.
//
// Exceptions:
// T:System.ArgumentException:
// alpha is less than 0 or greater than 255.
public static Color FromArgb(int alpha, Color baseColor);
//
// Summary:
// Creates a System.Drawing.Color structure from the four ARGB component (alpha,
// red, green, and blue) values. Although this method allows a 32-bit value to be
// passed for each component, the value of each component is limited to 8 bits.
//
// Parameters:
// alpha:
// The alpha component. Valid values are 0 through 255.
//
// red:
// The red component. Valid values are 0 through 255.
//
// green:
// The green component. Valid values are 0 through 255.
//
// blue:
// The blue component. Valid values are 0 through 255.
//
// Returns:
// The System.Drawing.Color that this method creates.
//
// Exceptions:
// T:System.ArgumentException:
// alpha, red, green, or blue is less than 0 or greater than 255.
public static Color FromArgb(int alpha, int red, int green, int blue);
//
// Summary:
// Creates a System.Drawing.Color structure from a 32-bit ARGB value.
//
// Parameters:
// argb:
// A value specifying the 32-bit ARGB value.
//
// Returns:
// The System.Drawing.Color structure that this method creates.
