RGB Function

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

RGB( _
   Red As Integer, _
   Green As Integer, _
   Blue As Integer _
)

Parameters

Red
Required. Integer in the range 0–255, inclusive, that represents the intensity of the red component of the color.
Green
Required. Integer in the range 0–255, inclusive, that represents the intensity of the green component of the color.
Blue
Required. Integer in the range 0–255, inclusive, that represents the intensity of the blue component of the color.

Exceptions/Errors

Exception type Error number Condition
ArgumentException 5 Green, Blue, or Red outside of range 0 and 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

Example

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