例子

VBA：

Sub Example_ColorIndex()
    'This example draws a circle and
    'returns the closest color index.

    Dim col As AcadAcCmColor
    Set col = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor." & Left(CStr(AcadApplication.Version), 2))
    col.SetRGB 125, 175, 235
    
    Dim cir As AcadCircle
    Dim pt(0 To 2) As Double
    Set cir = ThisDrawing.modelSpace.AddCircle(pt, 2)
    cir.TrueColor = col
    ZoomAll
    
    Dim retCol As AcadAcCmColor
    Set retCol = cir.TrueColor
    
    If col.ColorMethod = AutoCAD.acColorMethodByRGB Then
    MsgBox "Closest ColorIndex=" & col.ColorIndex
    End If

End Sub
