Help:Using colours
 | This help page is a how-to guide. It explains concepts or processes used by the Wikipedia community. It is not one of Wikipedia's policies or guidelines, and may reflect varying levels of consensus. |
 | Links should clearly be identifiable as links to readers. Refrain from implementing coloured links that may impede user ability to distinguish links from regular text, or colour links for purely aesthetic reasons. See the guides to editing articles for accessibility at contrast, accessibility and navbox colors. |
To use a colour in a template or table you can use the hex triplet (e.g. bronze is #CD7F32) or HTML color names (e.g. red).
Editors are encouraged to make use of Brewer palettes for charts, maps, and other entities, using this tool.
Overriding font colour
[edit]To make a word have colour, use:
<span style="color:hex triplet or colour name">text</span>
Note that you can't use the British spelling, "colour", in this context.
Examples:
<span style="color:red">red writing</span>shows as red writing<span style="color:#0f0">green writing</span>shows as green writing<span style="color:#0000FF">blue writing</span>shows as blue writing
Template font colour
[edit]Template:Font color, or its redirect Template:Font colour, can also be used.
{{Font colour|fontcolour|backgroundcolour|Your text here}}
| Markup | Renders as |
|---|---|
{{font color|red|This text is different}} |

{{font color|red|yellow|This text is different}} |

Colour generation guide
[edit]- The method used for selecting the colours for various top-level pages, e.g. Main Page, Community Portal, Contents, and Help:Contents.
The 3 colours are generated using the HSV colour space, then translated into RGB.
| Hue | Saturation 4% Brightness 100% main background |
Saturation 10% Brightness 100% 2nd header, accent colour |
Saturation 15% Brightness 95% main border header background |
Saturation 15% Brightness 75% header border only |
|---|---|---|---|---|
| Note: for layouts with no spacing between borders, use the darker border colour. | ||||

Wikimedia colour schemes
[edit]Wikipedia
[edit]Wikipedia uses this colour scheme on its Main Page.
| Hue: 150 | background:#F5FFFA border:#CEF2E0 | background:#CEF2E0 border:#A3BFB1 | ||
| Hue: 210 | background:#F5FAFF border:#CEE0F2 | background:#CEE0F2 border:#A3B1BF | ||
| Hue: 270 | background:#FAF5FF border:#E0CEF2 | background:#E0CEF2 border:#B1A3BF | ||
| Hue: 330 | background:#FFF5FA border:#F2CEE0 | background:#F2CEE0 border:#BFA3B1 |
And additionally on the Community Portal:
| Hue: 030 | background:#FFFAF5 border:#F2E0CE | background:#F2E0CE border:#BFB1A3 |
Additional 3-colour palettes using this same generation scheme are at the top of the talk page. In the Monobook skin, the background colour of Wikipedia pages is #F8FCFF. In the Vector skin, the background colour on all pages is #FFFFFF.
Commons
[edit]The Wikimedia Commons uses this colour scheme on commons:Main Page and commons:Help:Contents. Differing from the English Wikipedia, Commons does not use an extra, darker colour for bordering the header. Also, the colour sets are not derived from a hue the way the above table does.

Schemes for colour-blind readers
[edit]Approximately 1 in 12 men and 1 in 200 women with Northern European ancestry have red-green colour blindness; this and other types affect people worldwide.[1] This table shows "safe" groups of colours which are distinguishable to most colour-blind people, although colour should never be used as the sole method to convey information.
See also Commons:Commons:Creating accessible illustrations for color blind friendly palettes.
| Colour 1 | Colour 2 | Colour 3 | Colour 4 | Colour 5 | Colour 6 |
|---|---|---|---|---|---|
| White | Yellow | Blue | Red | Black | Grey |
| Green | |||||
| Lime | Purple | Brown | Cyan | ||
| Orange | Pink |
- Pick a maximum of one colour from each column. Do not use more than one colour from any one column.
- Use large expanses of the colour. If you're colouring text, use bold and a large font.
- For small expanses of colour, such as thin lines, clearly label them with text, or use non-colour techniques such as font styles (bold or italic), line styles (dots and dashes) or cross-hatching (stripes, checkers or polka-dots).
- Use bright mid-range colours, like children's crayons. Do not use light or dark variants of the colours.
- If you need more colours... hard luck. Instead use non-colour techniques such as labelling, font styles (bold or italic), line styles (dots and dashes) or cross-hatching (stripes, checkers or polka-dots).
- If you are colour-blind yourself, check your revised image with a colour-sighted person to confirm the meaning is intact.
The following utilities may be of use in determining whether a revised image is distinguishable to colour-blind users. Typically they take a web page or image file as an input, and render a colour-blind simulated image as output:
- Mozilla Firefox color-blind addons
- Sim Daltonism simulates color blind vision and displays the results in a floating palette for macOS and iOS. Freeware.
- Color Oracle downloadable, free color blindness simulator for Windows, Mac and Linux. Freeware.
Colour ramps
[edit]The standard rainbow should not be used to represent continuous data, because it creates artificial thresholds; humans do not see the spectrum as a smooth ramp. Greyscales, or a perceptually-even colour ramps, or a colour map chosen to deliberately highlight certain features, are preferable. Diverging colour ramps (two colour extremes around a white or black neutral value) tend to hide some high-frequency features.
Colours have cultural connotations; pick ones that match your data. That is, a diverging colour ramp with extremes "hot, cold" will be easier to understand than the reverse (hot, cold).
