Convert A Cell's Interior Color Code to RGB Format

When you issue the following command from the Immediate Windows of the VBE (Visual Basic Environment), you receive a long integer which defines the color of the cell:

? ActiveCell.Interior.Color

At times it is useful to convert that long integer into the RGB format so that, for example, you can assign a cell's interior color using a statement such as ActiveCell.Interior.Color = RGB(238,44,189)

The following code illustrates the method to convert from the long integer to RGB:

Program Code

Option Explicit

Public Sub ConvertColorCodeToRGB()
' ******************************************************************
' Select the Cell From Which You Want to Know the RGB Color Values
' Then Run This Macro To Display the RGB Values
'
' The Code in this macro could be condensed but was written in
' "full form" to allow easy viewing of all processes.
' ******************************************************************

' ******************************************************************
' Note:  In Excel 2003, you can only set a limited number of colors
'        using ActiveCell.Interior.Color = RGB(Red, Green, Blue)
'        where Red, Green and Blue each range from 0 to 255 decimal.
'        This limitation is due to the limits of pallet colors.
'
'        In Excel 2007 and above, you can set any combination of
'        Red, Blue and Green colors (Over 16 million colors)
' ******************************************************************
Dim lngColorIntegerCode As Long
Dim strHexCode As String

' ******************************************************************
