 The declaration of color charts to be used still have to be given "manually" in subroutine [../userinterface#user_dvrp_coltab user_dvrp_coltab] (file {{{user_dvrp_coltab.f90}}}).

+Parameter, which allows to bind the displayed particle color to certain flow quantities.
+
+By default, particles have a black color.
+
+Allowed values for particle_color are:
+
+'absuv'         Particle color depends on the absolute value of the resolved-scale horizontal velocity (SQRT(u2+v2) at the particle position.
+'pt*'   Particle color depends on the deviation of the resolved-scale potential temperature at the particle position from the horizontally averaged potential temperature (total domain).
+'z'     Particle color depends on the height of the particle with respect to the bottom boundary (z=0).
+
+The colortable used for particles ranges from deep blue to deep red with yellow in between. The interval of values from the above listed quantities to be mapped to these colors is defined by parameter color_interval.
+
+Example:
+If particle_color = 'pt*' and color_interval = -0.5, +0.5, then all particles at positions with pt* <= -0.5 K will have a deep blue color and those at positions with pt* >= +0.5 K will have a deep red color, while those with -0.5 < pt* < +0.5 will vary in color from deep blue to deep red and transition from yellow to blue indicate pt* ~ 0.0.
