colour coding velocity components in paraview
 

Hi,

I would like to plot the colour coded radial component of velocity (Ux) on a slice through my domain. I want this velocity component to be colour-coded such that positive values of Ux are coloured in red and negative values are coloured in blue, with the respective shades getting darker for more positive and more negative values (imagine white centred at zero).

How can this be done in paraview? I'm using paraview 5.4.1.

I want to use this kind of colormap as a background to my streamline plot. I have been unsuccessful so far. Any help will be appreciated.
