It's supposed to show the standard color dialog (ChooseColor API in comdlg32.dll).
For convenience, here's the code:
Private Type ChooseColorStruct
lStructSize As Long
hwndOwner As Long
hInstance As Long
rgbResult As Long
lpCustColors As Long
flags As Long
lCustData As Long
lpfnHook As Long
lpTemplateName As String
End Type
Private Declare Function ChooseColor Lib "comdlg32.dll" Alias "ChooseColorA" _
(lpChoosecolor As ChooseColorStruct) As Long
Private Declare Function OleTranslateColor Lib "oleaut32.dll" (ByVal lOleColor _
As Long, ByVal lHPalette As Long, lColorRef As Long) As Long
Private Const CC_RGBINIT = &H1&
Private Const CC_FULLOPEN = &H2&
Private Const CC_PREVENTFULLOPEN = &H4&
Private Const CC_SHOWHELP = &H8&
Private Const CC_ENABLEHOOK = &H10&
Private Const CC_ENABLETEMPLATE = &H20&
Private Const CC_ENABLETEMPLATEHANDLE = &H40&
Private Const CC_SOLIDCOLOR = &H80&
Private Const CC_ANYCOLOR = &H100&
Private Const CLR_INVALID = &HFFFF
' Show the common dialog for choosing a color.
' Return the chosen color, or -1 if the dialog is canceled
'
' hParent is the handle of the parent form
' bFullOpen specifies whether the dialog will be open with the Full style
' (allows to choose many more colors)
' InitColor is the color initially selected when the dialog is open
' Example:
' Dim oleNewColor As OLE_COLOR
' oleNewColor = ShowColorsDialog(Me.hwnd, True, vbRed)
' If oleNewColor <> -1 Then Me.BackColor = oleNewColor
Function ShowColorDialog(Optional ByVal hParent As Long, _
Optional ByVal bFullOpen As Boolean, Optional ByVal InitColor As OLE_COLOR) _
As Long
Dim CC As ChooseColorStruct
Dim aColorRef(15) As Long
Dim lInitColor As Long
' translate the initial OLE color to a long value
If InitColor <> 0 Then
If OleTranslateColor(InitColor, 0, lInitColor) Then
lInitColor = CLR_INVALID
End If
End If
'fill the ChooseColorStruct struct
With CC
.lStructSize = Len(CC)
.hwndOwner = hParent
.lpCustColors = VarPtr(aColorRef(0))
.rgbResult = lInitColor
.flags = CC_SOLIDCOLOR Or CC_ANYCOLOR Or CC_RGBINIT Or IIf(bFullOpen, _
CC_FULLOPEN, 0)
End With
' Show the dialog
If ChooseColor(CC) Then
'if not canceled, return the color
ShowColorDialog = CC.rgbResult
Else
'else return -1
ShowColorDialog = -1
End If
End Function

There is a color-picker built into VB6. The common dialog control can be used as a color picker.
Here's the code example from the VB6 manual
Private Sub Command1_Click()
' Set Cancel to True
CommonDialog1.CancelError = True
On Error GoTo ErrHandler
'Set the Flags property
CommonDialog1.Flags = cdlCCRGBInit
' Display the Color Dialog box
CommonDialog1.ShowColor
' Set the form's background color to selected color
Form1.BackColor = CommonDialog1.Color
Exit Sub
ErrHandler:
' User pressed the Cancel button
End Sub
