Help:Using colours

From Wikipedia, the free encyclopedia
(Redirected from H:Colorblind)

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}}

Example Result
  {{font color|red|This text is different}} This text is different
to change text-color only (Note: do not style text as a link)
  {{font color|red|yellow|This text is different}} This text is different
to change text and background color
  {{font color||yellow|This text is different}} This text is different
to change background color only

Wikimedia colour schemes

[edit]

Wikipedia

[edit]

Wikipedia uses this colour scheme on its Main Page.

Note: the colour for the border of the lighter boxes is also the colour of the backgrounds of the darker (title) boxes.
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.

background colour: #d0e5f5

background colour: #f1f5fc

border colour: #abd5f5
background colour: #faecc8

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.

  • 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:

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).
