How do I specify the RGB values for a link in Gazebo?
What I have found is you can specify a colour for the link using:
<gazebo reference="bottom_link">
<material>Gazebo/White</material>
</gazebo>
What I would like to know is that can I specify specific RGB values to get any colour I want?
I am using Gazebo 9.19.0 on ROS Melodic
