Hello @lwidowski,

Yes, that’s an error on our side. Meanwhile we solve it, I suggest you create the launch file in a package of yours and launch it from there. Here you have the contests of the launch file:

<launch>

    <arg name="image_topic" default="/camera/rgb/image_raw"/>

    <node name="color_gui_node" pkg="cmvision" type="colorgui" respawn="false"

    output="screen">

        <remap from="image" to="$(arg image_topic)"/>

    </node>    

</launch>

Best,
