/*!
    函数: Dlg_Color(ByRef r_Color,WinTitle="", hOwner:=0, Palette*)---->显示用于选择颜色的标准窗口对话框。

    参数:
        r_Color - 初始颜色-->默认设置为黑色.返回结果集{RGB:",BGR:"",RRGGBB:"}
        WinTitle - 自定义窗口标题，默认标题为「颜色」
        hOwner - 对话框对象的窗口ID, 如果有的话默认为0, i.e. 没有对象. 如果指定的DlgX和DlgY被忽略.
        Palette -最多16个BGR颜色值的数组。这些将成为对话框中的初始自定义颜色。
    Remarks:
        对话框中的自定义颜色在调用时被标记。如果用户选择OK，则将加载调色板阵列（如果存在）使用对话框中的自定义颜色。
    Returns:
        如果用户选择“确定”，返回True。否则返回False
