When selecting geometry by the name attribute in the viewport, the comparison between the viewport of Houdini 21 Valkan and Houdini 20 OpenGL is shown in the figure. The wireshaded mode of the Valkan viewport is completely unusable, and the selected face is not clear in wire mode. It is not as contrasting as the OpenGL viewport of Houdini 20.

I think you will have much more success if you turn off the default colours the group list window has.
