This template determines the pair of colors with the larger contrast ratio: color1/color2 or color1/color3. This is useful for selecting a foreground/background color pair. For accessibility, WCAG 2.0 AA guidelines require a contrast ratio of 3 or larger for large text, and 4.5 or larger for normal sized text.
In the default mode, color2 and color3 are white and black, and the selected color pair will always have a contrast ratio greater than 4.58.

|1=(required): background color|2=first fontcolor. Optional, default = white (#FFFFFF)|3=second fontcolor. Optional, default = black (#000000)
- The template returns the fontcolor with the greatest contrast
- background is موضيل:Legend inline: {{Greater color contrast ratio|khaki|white|black}} → black
- background is موضيل:Legend inline: {{Greater color contrast ratio|#4169E1|FFFFFF|000000}} → FFFFFF (=white)
- css text
|css=ymakes the template return css-ready text:
- موضيل:Legend inline:
{{Greater color contrast ratio|khaki|white|black|css=y}} - → background-color:khaki; color:black;
- موضيل:Legend inline:
- Example 1, موضيل:Legend inline
<span style="font-size:110%; {{Greater color contrast ratio|khaki|white|black|css=y}}">Example text on khaki background.</span>- →
<span style="font-size:110%; background-color:khaki; color:black;">Example text on khaki background.</span> - → Example text on khaki background.
- Example 2, موضيل:Legend inline
<span style="font-size:110%; {{Greater color contrast ratio|#4169E1|#ffffff|#000000|css=y}}">Example text on #4169E1 background.</span>- →
<span style="font-size:110%; background-color:#4169E1; color:#ffffff;">Example text on #4169E1 background.</span> - → Example text on #4169E1 background.
- bias
|bias=number: reduces contrast-check. A bias of 1.25, reduces the possible minimum to 4.0, which may not meet accessibility standards.
- This parameter should be used with caution to ensure accessibility. As stated above, when used without a bias, and with color2 and color3 equal to white and black, the selected color pair will always have a contrast ratio greater than 4.58.
