A few weeks ago a new document appeared on the TfL website, announcing the design rules that will apply to the new Elizabeth line signage.
It was due to be released earlier this year, but someone changed the name of the line, so the Crossrail design idiom had to be rewritten. This is now version 2 of the document.
What emerges is a fairly standard rule book that’s not prescriptive, but makes strong suggestions about how Elizabeth line signs and maps should be drawn.
The colour purple is the dominant one, and is officially designated as Pantone 266c.
Strong is the use of the colour purple on the line, although, at 40% of the tube roundel, it’s only just ahead of white (35%), and then there’s the classic TfL Blue for the name — at 25% of the sign.
That rough ratio will be retained across all Elizabeth line signs going forwards.
Unsurprisingly, they are using Johnston100 as the font, which is the official font for all TfL services.
Considering the fuss over the change of the name, and rumours of a TfL swear jar whenever someone at headoffice calls it Crossrail, page 8 of the document might be a bit awkward.
