While {{Overcoloured}} will display the date (e.g. List of Total Wipeout episodes), {{Overcolored}} does not (e.g. Wipeout (2009 Australian game show)). Could someone please fix this? Thanks! GoingBatty (talk) 02:36, 11 March 2013 (UTC)[reply]

 Done the parameter wasn't passed through. --Redrose64 (talk) 09:08, 11 March 2013 (UTC)[reply]

Thank you for continuing to resolve my requests! GoingBatty (talk) 16:39, 11 March 2013 (UTC)[reply]

There is no need for two separate, same templates. Gamingforfun³⁶⁵ (talk) 18:24, 24 October 2015 (UTC)[reply]

How do you propose to handle UK/US spelling differences? --Redrose64 (talk) 22:33, 24 October 2015 (UTC)[reply]

It is not that I dislike the template for its British spelling; it is only that these two templates have the same function. Surely, the template may be appropriate for British English readers, but that is just it. The only difference is the spelling, and that may although very insignificantly clog the Wikipedia servers. My point is that we have no need to have duplicates of templates with only a few minor changes, although I may be quest as to why I had picked this template instead of the other.

But some people like the idea of having the spelling difference. I just do not see why we must have it. Do you? Gamingforfun³⁶⁵ (talk) 03:15, 25 October 2015 (UTC)[reply]

It's not a duplicate. {{Overcolored}} is a wrapper for {{overcoloured}} with |US=y forced. --Redrose64 (talk) 08:51, 25 October 2015 (UTC)[reply]

I have used this template (perhaps incorrectly) in templates, such as the Template:London Heathrow Airport navbox, which have colour issues. Unfortunately it doesn't add the templates to the Category:Wikipedia articles with colour accessibility problems. Can it be updated to be used on templates? Cnbrb (talk) 22:03, 5 September 2017 (UTC)[reply]

@Cnbrb: It's not necessary. The navbox code includes contrast checks (to a limited extent) and the page is automatically placed in Category:Navboxes using background colours. --Redrose64 🌹 (talk) 08:07, 6 September 2017 (UTC)[reply]

@Redrose64: Oh thanks I had no idea. So is this (rather huge) category patrolled by accessibility police? I suppose I'm just keen for these templates to be marked for review. Cnbrb (talk) 08:14, 6 September 2017 (UTC)[reply]

Much of the backlog dates back to before Module:Color contrast was incorporated into Module:Navbox, but another factor contributing to the size of the category is that some people - particularly sports fans - insist on navboxes being coloured to suit the primary topic of the navbox. {{London Heathrow Airport}} is actually quite mild, and I find it readable - the worst cases (see for example {{1955/56/57 Melbourne triple premiership players}}) end up in Category:Potentially illegible navboxes. --Redrose64 🌹 (talk) 09:51, 6 September 2017 (UTC)[reply]

I agree, it's not a bad case - still worth checking it though. But then again, I have seen some perfectly acceptable boxes that test completely fine in all my contrast filters still being de-colourised by accessibility police, so I tend to err on the side of caution. Yes, sports teams, religion and London Underground lines! And that Melbourne template is an abomination!! Cnbrb (talk) 11:37, 6 September 2017 (UTC)[reply]

{{London Heathrow Airport}} uses two background colours and two foreground colours, but only three of the possible four combinations are found:

•  Plain text  black on lightsteelblue, for which the contrast ratio is 11.8 which is above the 7.0 requirement for WCAG 2 AAA Compliance
•  Linked text  blue on lightsteelblue, for which the contrast ratio is 4.79 which is WCAG 2 AA Compliant but not WCAG 2 AAA Compliant
•  Plain text  black on #D0DAE7, for which the contrast ratio is 14.86 which is way above the 7.0 requirement for WCAG 2 AAA Compliance.

The religion people usually confine their colours to a pair of horizontal lines - the top and bottom border of the title row, which ordinarily has a white background. London Underground lines also restrict the colour - in this case to a pair of coloured rectangles, achieved by setting the left and right borders of the title row to 2.7em wide, which otherwise uses the default background. --Redrose64 🌹 (talk) 20:38, 6 September 2017 (UTC)[reply]

I frequently see images of charts or maps where the only distinguishing characteristic is color. Can I add this template directly to the image's Wikimedia Commons page, since it may be linked on multiple articles?
