One of the icon sets installed in Koha includes a series of colors. This set can be used to catalog and search by color if you'd like. This guide will walk you use changing collection code to color in Koha so that you can do this.

The following SQL could be used to add these colors to the CCODE authorized value category in a batch. If you wanted to use these colors for another authorized value you'd have to edit this to use that category:

    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','000000','Black','','colors/000000.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','66cc66','Bright Green','','colors/66cc66.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','99cc33','Olive','','colors/99cc33.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','3333cc','Dark Blue','','colors/3333cc.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','006600' ,'Dark Green','','colors/006600.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','6600cc','Plum','','colors/6600cc.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','6666cc','Purple','','colors/6666cc.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','9999cc','Light Purple','','colors/9999cc.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','660000' ,'Burgundy','','colors/660000.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','663333' ,'Brown','','colors/663333.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','990000' ,'Red','','colors/990000.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','996633' ,'Tan','','colors/996633.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','999999' ,'Gray','','colors/999999.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','cc66cc','Pink','','colors/cc66cc.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','cc99cc','Bubble Gum','','colors/cc99cc.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','cc3333' ,'Orange','','colors/cc3333.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','cc6666' ,'Peach','','colors/cc6666.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','cc9999' ,'Rose','','colors/cc9999.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','cccc00' ,'Gold','','colors/cccc00.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','ffff33' ,'Yellow','','colors/ffff33.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','ffffcc','Cream','','colors/ffffcc.png');
    insert into authorised_values (category, authorised_value, lib,
     lib_opac, imageurl) values ('CCODE','ffffff','White','','colors/ffffff.png');

If you would like to choose the colors manually you can do that via the Authorized Values administration area.

Next you'll want to update the frameworks so that the 952$8 (if you're using collection code) label to says Color.

Once you have that in place you can start to catalog items by color.

Finally you'll want to add the following JQuery to your preferences so that it will relabel 'Collection' to 'Color'

IntranetUserJS

$(document).ready(function(){
    $("#advsearch-tab-ccode a:contains('Collection')").text("Color");
    $("#holdings th:contains('Collection')").text("Color");
    });

OPACUserJS

$(document).ready(function(){
    $("#advsearch-tab-ccode a:contains('Collection')").text("Color");
    $('#item_ccode').text("Color");
    });
