[Qgis-user] delimited text point cloud color attribute ?

[friedtj at free.fr]

I am sure this is a trivial question by I am unable to locate the solution on the
web after a couple of days of searching :
I have a point cloud defined with coordinates and RGB color attributes, ie a file with

X            Y            Z            R   G   B
508.71444702 255.17164612 316.63302612 254 254 254
508.85519409 255.27404785 316.73541260 254 254 254
508.86724854 255.21253967 316.71292114 252 254 254
508.92807007 255.21278381 316.73757935 247 251 253

I can load this file using the Add Delimited Text Layer tool, and at the moment I
use the Z elevation attribute to color my point cloud in QGis (Properties -> Graduated
in Symbol option and Column = Z). I would like now each point to be colored by the RGB
attribute: how can I do this ? I know this is trivial for raster layers, but I cannot
find the solution for a vector layer.

Thanks, Jean-Michel
