Editing Tube map (section)

===Line colours===
The table below shows the changing use of colours since Beck's first map. The current colours are taken from Transport for London's colour standards guide,<ref name="ColourStandardNov24">{{cite web |author1=Transport for London |author1-link=Transport for London |title=Colour standard |url=https://content.tfl.gov.uk/tfl-colour-standard.pdf |website=Transport for London |access-date=18 March 2025 |archive-url=https://web.archive.org/web/20250311200745/https://content.tfl.gov.uk/tfl-colour-standard.pdf |archive-date=11 March 2025 |version=Issue 9 |date=November 2024 |url-status=live}}</ref> which defines the precise colours from the [[Pantone]] palette and also a colour naming scheme that is particular to TfL. Earlier maps were limited by the number of colours available that could be clearly distinguished in print. Improvements in [[colour printing]] technology have reduced that problem and the map has coped with the identification of new lines without great difficulty.
