<div dir="auto">I have gone that far, but I have four sets of maps with similar units. If I categorize them independantly, I have to manually change the colours to make them consistent between layers. This is very time consuming and I was wondering if the colour can added to the attribute table so that I can edit them more easily </div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Jun 21, 2022 at 2:56 AM <<a href="mailto:geo.guide@web.de">geo.guide@web.de</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="font-family:Verdana;font-size:12.0px"><div>Context menu of your shapefile > properties > choose Tab "Symbology" > select "Categorize" in the first line with the attribute for the name of the geologic formation as the value in the second line.

<div>i have four different geologic maps that i have imported as shapefiles. The files have filled polygons that have the name of the geologic formation in the attribute tables. i would like to have a common colour for each polygon of identical age/name for all the map sheets. Each map sheet has a similar list of formations, but some of the formations are different for each map sheet.
<div>What is the most efficient way to make the identically named polygons displayed with the same colour? Should i add a column in each attribute table and put a formation code in for each one manually or can i add an RGB colour for each formation in the attribute table? or, do i need to categorize and classify these in the layer properties table after i have added formation code in the attribute table?</div>
<div>i hope that my question is clear.
