This template can be used to call the color of Klang Valley Rail Transit lines in and around Kuala Lumpur. The following are included in this template.
In order to call a line's color, the code <nowiki>{{rcr|KLRT|</nowiki><i>line</i><nowiki>}}</nowiki> is used (where line is replaced by the actual line number or color). Note that this template is not case sensitive: i.e. <nowiki>{{rcr|KLRT|Red}}</nowiki> produces the same result as <nowiki>{{rcr|KLRT|red}}</nowiki>.
Colors were obtained from the MRT3 Circle Line map at www.mymrt.com.my: MRT Corp or KTMB's GTFS static data
