Why the text color of the frame's name in rviz is white?

Is it white because that background of the rviz is black? If yes, what if we change it to white? Can we change the text color of the frame's name in rviz to black? If yes, how?

I change background of the rviz from black to white easly, but the text color of the frame's name is impossible to change it from rviz screen. Which is file of configuration whose is responsible for it?

This is basically hard-coded in the tf display type plugin:

("basically", because in case of a timeout it will turn grey...)

So there is no way for you to change that except for changing the source code.

As to why it is white in the first place, my guess is as good as any, but I'd also say due to the default background being black...

I did not find tf_display.cpp in my computer, but I found tf_display.h which does not include color's lines.

I will add figure to my question as update. Will I need to build it as own visualization from source? If yes, does it need to modify something in launch file?

I downloaded it for kinetic from kinetic-devel and put it on my /catkin_ws/src/

I changed this line from




and used catkin_make,

then used source ~/catkin_ws/devel/setup.bash

It works fine,

thank you so much for your help.

Note: all this modification is in the workstation part, not is in the robot part.
