现有RGB：static COLORREF clrAuto = RGB(255, 255, 255);

<1>COLORREF格式的RGB转换为CString格式：_T("%d, %d, %d")

static CString FormatColor(COLORREF color)
{
    CString str;
    str.Format(_T("%d, %d, %d"), GetRValue(color), GetGValue(color), GetBValue(color));
​
    return str;
}

<2>将RGB的CString格式转换为COLORREF

static COLORREF GetColorRGB(const CString& strColorText)
{
    COLORREF color;
    char chR[6] = "", chG[6] = "", chB[6] = "";
    std::string str = CStringA(strColorText);
    const char* chColor = str.c_str();
    scanf(chColor, "%[^,],%[^,],%[^,]", chR, chG, chB);
    color = RGB(atoi(chR), atoi(chG), atoi(chB));
    return color;
}
