fantastic, that did it, I was not aware of the color_rgb() functionnality in the Expression Builder.
Thanks a lot.

You can do this by using a data defined properties. Go in to layer properties Select the Style tab Pick a single symbol as the marker type In the bottom left of the dialog is the symbol layers panel. Click the "Simple marker" Then in the panel to the right click "Data defined properties" This will bring up the data defined properties dialog box Click the fill color check box, and then click the [...] button to the right of it (expression) This will get you into the Expression string builder Click on the Color> group to expand it out, then enter the following in the "Expression box" color_rgb("R","G","B") Then click Ok as many times as necessary to get out .. this should do it. Sounds complicated, but makes more sense when you do it than when you try to write it down!

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.
