<p>Good Morning Everyone,</p>
<p>With all the users who have tested so far we could assess the
following:</p>
<ol>
<li>If you go to the layer properties and choose the "Categorized"
style and the "Colour" column, without doing any classification
before that then it shows the correct colour on the map and also
the legend. The problem with that is that you then have only the
hex colours in your legend and still need to look up each
"Chronostra" code in the table to insert it into the
legend...same work as setting the colour manually. The other
problem is that e.g. "Rc" and "Rw" have the same colour, but are
different lithologies (although they are related), and therefore
show only once in the legend, but both "Rc" and "Rw" should show
in the legend (with the same colour).</li>
<li>If you use "Categorized" and choose the "Chronostra" column
and then go to "Symbol|Simple Fill" and set the colour to the
"Colour" field then you get the correct colours on the map, but
the legend colours are wrong (but at least you have all the
"Chronostra" items in your legend.</li>
</ol>
<p>I will lodge this as a bug as all the options are there to set
the colours and legend, but it does not produce the correct
results.</p>
<p>I would also like to request a feature on the attribute tables,
which one can put on the composer. It would be a great advantage
if one could colour rows or columns or just cells according to the
value they represent. So one could colour the cell with the
"Chronostra" text according to the colour field! (Another great
way of displaying table info as a legend.<br>
</p>
<p>Regards</p>
<p>Immo<br>

I experience the same behaviour you describe...I am able to get
the colours to display correctly on the map (using data-defined
override and referring to the "colour" column) but cannot get the
legend to show the correct colours without manually editing the
legend. I tried on both QGIS 2.14.16 on Ubuntu 16.04 and QGIS
2.18.10 on Widows 7. Looks like this issue is a known one - see
here:

<br>
<br>
Best work-around for the moment, if it is a dataset you use a lot,
seems to be to manually sort the legend out and then save the
style for future use in other projects.
<br>
<br>
Perhaps you should add this to the feature requests for QGIS??

Could you send us a copy of the layer you are trying to render

help with the testing...

Good Morning Everyone,
<br>
<br>
I have a geology layer with a few columns, including the
chronostratigraphic symbol, the rock type description
and, importantly, a colour column (String type). The
values stored in the colour column are the HTML hex
values for the colour according to the 1 : 1 000 000
simplified geological map of South Africa.
<br>
<br>
When I open the layer and select the colour column for
colouring the lithological units it works beautifully,
but I do not get a legend for the composer. But if I set
the Properties|Style to Categorized and then again
select the colour from the Colour column in the table I
also get the same nicely coloured map according to the
colour column, an a Legend. But the Legend is wrong...it
chooses random colours! What am I doing wrong? Is there
a way to get a correct legend, also only showing the
units which are actually on the map in the composer. I
can set the colours manually to match the value in the
colour field but that sort of defeats the purpose.
<br>
<br>
Thanks for your help so long,
<br>
<br>
Immo
