'Break out the R, G, B values from the common dialog color
lCol = lCdlColor
iRed = lCol Mod &H100
lCol = lCol \ &H100
iGreen = lCol Mod &H100
lCol = lCol \ &H100
iBlue = lCol Mod &H100
'Determine Red Hex
vHexR = Hex(iRed)
If Len(vHexR) < 2 Then
vHexR = "0" & vHexR
End If
'Determine Green Hex
vHexG = Hex(iGreen)
If Len(vHexG) < 2 Then
vHexG = "0" & iGreen
End If
'Determine Blue Hex
vHexB = Hex(iBlue)
If Len(vHexB) < 2 Then
