On the right are four maps that are representative of issues I’ve seen in FA or GA in the past several weeks. For all these maps, editors were unsure whether the map overlay colors were consistent with [[MOS:COLOR]]. The confusion is whether hue (red/blue/green/yellow/orange) is acceptable for conveying information in the graphic overlay. |

I have seen a lot of confusion in WP:Featured Articles and WP:Good Articles over how to apply the MOS:COLOR accessibility guideline to graphic overlays in maps. MOS:COLOR says:
- “When using color, editors should keep accessibility for users with low vision impairments and color blindness in mind:… Color should not be used as the sole visual means of conveying information, or for distinguishing elements such as links, templates, or table rows. Always provide an alternative method” [such as icons, symbols, etc] [emphasis added].
On the right are four maps that are representative of issues I’ve seen in FA or GA in the past several weeks. For all these maps, editors were unsure whether the map overlay colors were consistent with MOS:COLOR. The confusion is whether hue (red/blue/green/yellow/orange) is acceptable for conveying information in the graphic overlay.
On the other hand, I think everyone agrees that color lightness – e.g dark blue/ medium blue/ light blue/white – is acceptable. Likewise, using dotted/dashed/solid line styles is acceptable.
WP:MOS says “New content added to this page [WP:MOS] should directly address a persistently recurring style issue.” I think this color issue is “persistently recurring” because I’ve seen it four times in the past six weeks, so I suspect that hundreds of editors are facing this issue monthly as they add or review maps within articles.
Therefore, I pose the question:
Should MOS:COLOR be updated to clarify if and when color hues (such as red/blue/green/yellow/orange) may be used for graphic overlays in maps?
Personally, I have no opinion on the matter. I raise the issue here only because it is clear that many editors are confused about how to apply MOS:COLOR to maps.
