Shows a legend row with a colored box.
__TOC__

==Usage==
<nowiki>{{</nowiki>legend|''background-color''|''caption''|outline=''outline color''|border=''css border''|alt=''alt text''<nowiki>}}</nowiki>

*''background-color'' is passed to the [[Cascading Style Sheets|CSS]] background-color property of the color box.
*The optional ''outline'' parameter is the color of the outline around the box. Not to be confused with the CSS outline property.
*The optional ''border'' argument which overrides the ''outline'' argument and sets the CSS property (e.g., <code>1px solid #aaa</code>) of the border that will be drawn around the box.

==Examples==
===Use in text===
{{demo|<nowiki>
{{legend|black|Africa|outline=gray}}
{{legend|green|Americas}}
{{legend|blue|Oceania}}
{{legend|#ffa|Europe|outline=silver}}
{{legend|#ff2800|Asia|outline=#A2A9B1}}
<!-- #A2A9B1 is the [[Help:Basic table markup|wikitables]] border color. -->
</nowiki>}}

===Use in captions===
{{markup|<syntaxhighlight lang="wikitext">
 [[File:Celts in Europe.png|upright=.9|thumb|right|The Celts in Europe, past and present:
 {{legend|#1a8000|Present-day Celtic-speaking areas}}

 {{legend|#D2FFD2|Lusitanian area of Iberia, "Celticity" uncertain}}

=== Use with all parameters except ''alt'' and ''invert'' ===
<syntaxhighlight lang="wikitext">
{{legend
| #ded <!--light green-->
| The meadow is green.
| outline   = #00e <!--blue >> will be not used because overridden by border-parameter-->
| border    = 2px solid #e00 <!--red-->
| textcolor = #00e <!--blue-->
| size      = 200%
| text      = green
}}
</syntaxhighlight>
{{legend
| #ded <!--light green-->
| The meadow is green.
| outline   = #00e <!--blue >> will be not used because overridden by border-parameter-->
| border    = 2px solid #e00 <!--red-->
| textcolor = #00e <!--blue-->
| size      = 200%
| text      = green
}}

===Invert in dark mode===
This is only for the [[WP:dark mode (gadget)|dark mode]]; nothing happens in the built-in [[WP:dark mode|dark mode]] since table colors are not inverted.
<syntaxhighlight lang="wikitext">
{{legend|#FFC7C7|No|invert=yes}}
{{legend|#FF8|Maybe|invert=yes}}
{{legend|#9EFF9E|Yes|invert=yes}}
</syntaxhighlight>
{{legend|#FFC7C7|No|invert=yes}}
{{legend|#FF8|Maybe|invert=yes}}
{{legend|#9EFF9E|Yes|invert=yes}}

==Full parameter list==
<syntaxhighlight lang="wikitext">
{{legend
| [legend box's colo(u)r]
| [text following legend box]
| invert =    <!--Invert the color swatch in dark mode-->
| outline =   <!--colo(u)r of border around legend box-->
| border =    <!--use to specify custom CSS styling for border (overrides 'outline')-->
| textcolor = <!--colo(u)r of 'text'-->
| size =      <!--'text' font-size-->
| text =      <!--to place text inside the legend box-->
| alt =       <!--to place invisible text inside the legend box (overrides 'text')-->
}}
</syntaxhighlight>

==Limitations==
Using certain special characters in {{para|text}} that have meaning in wikitext can cause unexpected results. To use {{asterisk}} in {{para|text}}, use {{para|text|{{tlf|asterisk}}}}. To use # in {{para|text}}, use {{para|text|{{tlf|number sign}}}}.

==Determine hex colors for legend==

One way to determine the exact color is via freeware [[IrfanView]]. Open image. Then:
:Edit menu > Show Paint dialog > click on the eyedropper > click somewhere in the image > click on the color at the bottom of the Paint dialog > Write down the Red, Green, and Blue color numbers (RGB).

Online sites that can identify the color of any pixel in an uploaded image are also available: 
*[https://imagecolorpicker.com/ imagecolorpicker.com]

Convert [[RGB colors]] to [[hex color]] or [[Web colors#HTML color names|color name]] (if there is one):
*[https://www.w3schools.com/colors/colors_converter.asp Color Converter].
