Table 3

The eight members of the VBA Color Constants class:

  • vbBlack
  • vbWhite
  • vbRed
  • vbGreen
  • vbBlue
  • vbYellow
  • vbMagenta
  • vbCyan



Example 1:

txtCon(cnt).BackColor = vbHighlightText

Example 2: This is the same as "Button Highlight"

txtCon(cnt).BackColor = vbHighlightText



Setting Form and Control Colors

  • Blue : Me.BackColor = RGB(0, 0, 255)
 Me.BackColor = RGB(0, 0, 255)
  • Green: Me.BackColor = RGB(0, 255, 0)
 Me.BackColor = RGB(0, 255, 0)
  • Red: Me.BackColor = RGB(255, 0, 0)
 Me.BackColor = RGB(255, 0, 0)

All Possible Ways

1. In HEX, BLUE is first, Green, then Red, the reverse of RGB (actually BGR) is the default VB method

 cmd(0).BackColor = &HFF&      ' Red   / &H0000FF&
 cmd(1).BackColor = &HFF00&    ' Green / &H00FF00&
 cmd(2).BackColor = &HFF0000   ' Blue  / &HFF0000&

2. Decimal RGB value

 cmd(0).BackColor = RGB(255, 0, 0)
 cmd(1).BackColor = RGB(0, 255, 0)
 cmd(2).BackColor = RGB(0, 0, 255)

3. Using VB Color Constants

 cmd(0).BackColor = vbRed
 cmd(1).BackColor = vbGreen
 cmd(2).BackColor = vbBlue

Convert RGB Hex (like used in HTML) to VB Hex

Code Sample:

Public Function h2v(wHex As String) As Long
  Dim strTmp As String
  wHex = Trim("" & wHex)
  If Len(wHex) = 7 Then
    If Left(wHex, 1) = "#" Then wHex = Right(wHex, 6)
  End If
  If Len(wHex) = 6 Then
    strTmp = "&H" & Right(wHex, 2) & Mid(wHex, 3, 2) & Left(wHex, 2) & "&"
    strTmp = "&H000000&"
  End If
  h2v = Val(strTmp)
  Debug.Print h2v
End Function
