<p class="MsoNormal"><span style="color:#1F497D">Hi Grant,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">What I meant is that, using the Field calculation you can create new fields for each thing you want to style. In your case you want a field for colour.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Using the field calculator you can set up a script, for example…<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">CASE <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"> WHEN "class" = 'Igneous' THEN '#fc9403'<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"> WHEN "class" = 'Sedimentary ' THEN '#03fc56'<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"> WHEN "class" = 'Igneous rocks' THEN '#7303fc'<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"> WHEN "class" = 'Metamorphic' THEN '#fc03e7'<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"> ELSE '#fc0303'<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">END<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">This will then assign a colour to each feature, which you can assign using the
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">This can be done for a lot of the styling options as I mentioned before.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">As I said below, and as you mentioned in your message, this
<b>won’t be reflected in the Legend</b>, only in the Map. The above probably isn’t the solution you are looking for.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Another suggestion is to look into creating a set of Standard Styles stored centrally. When you load a Layer into Qgis you can load these styles as required, which will apply the rules you previously set.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">You can also create default styles for a particular layer and every time you load the layer into a Project the style is automatically loaded with the layer. You can do this from in the Layer Properties and going
down to the <b>Style</b> Button selecting <b>Save as default</b><o:p></o:p></span></p>
