issue when using gui.setColor() in python

[hammoudbilal]

Hi,

I'm trying to change the colors of visual objects using gui.setColor(nodeName, [r,g,b,a])
this used to work fine until recent update, now it seems to work only if I add a mesh with an stl extension

• if I add a mesh with .dae or use something like gui.addCone(,,, [r,g,b,a]) then what ever rgb scale I use it shows in black
• if I check the body tree in the gepetto-gui and I click on the color of an object within the tree then it displays the values I used (you can see in the figure below some shade of orange) however it displays it in black
  

is there anything I might be doing wrong ?

I can't reproduce your issue. If I do

from gepetto.corbaserver import gui_client
gui = gui_client(window_name="t")
gui.addCone('t/c', 0.1, 0.1, [0.5, 0.5, 0., 1.])

I get a cone with a yellow-green color.

Do you have a minimal reproducible example ?
