Namespace: Microsoft.VisualBasic
Assembly: Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

public static int RGB(
	int Red,
	int Green,
	int Blue
)

Parameters

Red: Type: System.Int32
Required. Integer in the range 0–255, inclusive, that represents the intensity of the red component of the color.

Green: Type: System.Int32
Required. Integer in the range 0–255, inclusive, that represents the intensity of the green component of the color.

Blue: Type: System.Int32
Required. Integer in the range 0–255, inclusive, that represents the intensity of the blue component of the color.

Return Value

Type: System.Int32
Returns an Integer value representing an RGB color value from a set of red, green and blue color components.

Exceptions

Exception	Condition
ArgumentException	Green, Blue, or Red is outside of range 0 to 255, inclusive.

Remarks

Application methods and properties that accept a color specification expect that specification to be a number representing an RGB color value. An RGB color value specifies the relative intensity of red, green, and blue to cause a specific color to be displayed.

If the value for any argument to RGB is greater than 255, 255 is used.

The following table lists some standard colors and the red, green, and blue values they include.

Color	Red value	Green value	Blue value
Black	0	0	0
Blue	0	0	255
Green	0	255	0
Cyan	0	255	255
Red	255	0	0
Magenta	255	0	255
Yellow	255	255	0
White	255	255	255

Examples

This example shows how the RGB function is used to return a whole number representing an RGB color value.

Dim red, rgbValue As Integer 
Dim i As Integer = 75
' Return the value for red.
red = RGB(255, 0, 0)
' Same as RGB(75, 139, 203).
rgbValue = RGB(i, 64 + i, 128 + i)
