Background
Using jQuery widgets and OpenLayers widgets on the same web page.
Problem
jQuery has Theme Roller while OpenLayers has its default theme. This results in:

The toolkit controls have different colours. This can be remedied by customizing either OpenLayers or jQuery to match the other, but I’d rather not re-invent the wheel if possible. For example:
- http://dev.openlayers.org/sandbox/itranga/openlayers/theme/css/jquery/
- http://trac.osgeo.org/openlayers/ticket/1800
- https://github.com/developmentseed/openlayers_themes
Question
Where can I find themes for OpenLayers 2.12 and jQuery UI 1.8.18 (that are freely available) that align their colour schemes?
Thank you!
You can use FireDebug (or equivalent) to inspect the UI elements. From there, change the colours of the UI elements with CSS.
