Get colored text with Popen

Question

I use popen to create a plugin, this plugin used an external program that displays colored text in the output.

The result looks something like this:

avr-g++ -o .pioenvs\uno\FrameworkArduino\HardwareSerial.o -c -std=gnu++11 -fno-exceptions -fno-threadsafe-statics -g -Os -Wall -ffunction-sections -fdata-sections -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO_ARCH_AVR -DARDUINO_AVR_UNO -DARDUINO=10607 -I.pioenvs\uno\FrameworkArduino -I.pioenvs\uno\FrameworkArduinoVariant .pioenvs\uno\FrameworkArduino\HardwareSerial.cpp    
avr-g++ -o .pioenvs\uno\FrameworkArduino\HardwareSerial0.o -c -std=gnu++11 -fno-exceptions -fno-threadsafe-statics -g -Os -Wall -ffunction-sections -fdata-sections -mmcu=atmega328p -DF_CPU=16000000L -DARDUINO_ARCH_AVR -DARDUINO_AVR_UNO -DARDUINO=10607 -I.pioenvs\uno\FrameworkArduino -I.pioenvs\uno\FrameworkArduinoVariant .pioenvs\uno\FrameworkArduino\HardwareSerial0.cpp
=============================================
Path\file.cpp: in function 'void loop()':
Path\file.cpp:23:2 error: expected ';' before '}' token
}
^
=============================================

Everything inside the "=" is in red and yellow.

When I run the command in the command console, I can see the full output, but when I use Popen, I can only get unpainted text

This is how I use Popen

process = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE, cwd=self.cwd, universal_newlines=True, shell=True)
output = process.communicate()

stdout = output[0]
stderr = output[1]

print(stdout)
print(stderr)

I would like to get the text, even if it is not colored, it is important to get the full journal.

Any suggestion will be appreciated.

stderr=subprocess.PIPE Popen, stderr:

process = subprocess.Popen(command, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE, cwd=self.cwd, universal_newlines=True, shell=True)
output = process.communicate()

stdout = output[0]
stderr = output[1]

print(stdout)
print(stderr)
