Text in TextClip in multiple colors

[przemeczek]

Is there a way to display a substring of the text specified in the TextClip constructor in a different color than the rest of the text?
To be clearer, what I want to achieve is this:

1. Say, I have this line of code in my script
   txt_clip = TextClip("Text Test",font="Tahoma-Bold", fontsize=70,color='black',stroke_width=5)
2. I want "Text" to be black and "Test" to be red in the final clip. How can I accomplish this?

Thanks!
