如何检测调用了我的 python 脚本的终端的当前背景颜色？

Question

I am using a xfce4 terminal and I want to be able to detect if the background color is set to either black or white (or presumably some other color)

My code looks like this:

def print_color(string, style, textColor, background):  
     string = "\033[{};{};{}m{}\033[m ".format(style,textColor,background,string)  
     print(string)

I would like to detect the current background color and use it instead of passing it in.

I've tried not setting it, like this:

def print_color(string, style, textColor):  
     string = "\033[{};{};m{}\033[m ".format(style,textColor,string)  
     print(string)

but that did not work as I expected.

XFCE4 terminal uses VTE, which lacks the ability to respond to queries of the colors. That would be the SGR flavor of DECRQSS , which is mostly unimplemented in VTE.

(The example shown wouldn't work anyway). This is unrelated to the GTK+ toolkit.
