BGUI change color for Text_Input how can I change the color of the text_input widget in the BGUI?

I've tried:

self.input = bgui.TextInput(self.win, text="text", color=(0, 0, 0, 1), size=[.4, .04], pos=[.04, 0.12],
        input_options = bgui.BGUI_INPUT_NONE, options = bgui.BGUI_DEFAULT)


but it didn't work, the color is still white. In the default theme the TextInput color is set to black too. 

Thanks in advance.
Looking at the code for BGUI, it appears that the color parameter is not being used in text_input.py. Your best option is to use theme to customize the input text color.
