如果要更改选择背景颜色，然后尝试:

If you want to change the selection background color, then try:

Win32.SendMessage(PluginBase.GetCurrentScintilla(),
                  SciMsg.SCI_SETSELBACK, 1, 0xFFFF00);

如果您要更改选择前景色，请尝试:

If you want to change the selection foreground color, then try:

Win32.SendMessage(PluginBase.GetCurrentScintilla(),
                  SciMsg.SCI_SETSELFORE, 1, 0xFF0000);

To reset the default color, pass 0 instead of 1.
