Colour contrast problems
It seems that this article is using colours in the infobox which don't satisfy Wikipedia's accessibility guidelines. The contrast between the foreground colour and the background colour is low, which means that it may be difficult or impossible for people with visual impairments to read it.

To correct this problem, a group of editors have decided to remove support for invalid colours from Template:Infobox television season and other television season templates after 1 September 2015. If you would still like to use custom colours for the infobox and episode list in this article after that date, please ensure that the colours meet the WCAG AAA standard.

To test whether a colour combination is AAA-compliant you can use Snook's colour contrast tool. If your background colour is dark, then please test it against a foreground colour of "FFFFFF" (white). If it is light, please test it against a foreground colour of "000000" (black). The tool needs to say "YES" in the box for "WCAG 2 AAA Compliant" when you input the foreground and the background colour. You can generally make your colour compliant by adjusting the "Value (%)" fader in the middle box.

Please be sure to change the invalid colour in every place that it appears, including the infobox, the episode list, and the series overview table. If you have any questions about this, please ask on Template talk:Infobox television season. MediaWiki message delivery (talk) 05:30, 2 August 2015 (UTC)
