Wikipedia:WikiProject Economics/Style guide
Appearance
This is a proposed standard for the layout and use of color in tables, templates, images, and large quotes in Wikipedia Economics articles. The goal is to give economic articles a similar appearance in order to aid navigation and lend the appearance of a more unified whole to the various Wikipedia articles. Another way to phrase this might be to say that the goal here should be to make the economic articles as a set look more like a single book and less like a collection of web pages cobbled together.
Among the proposals on this page you will find a proposed color scheme. The following colors should be used in all tables, charts, and templates:
Default background color: #F4F4FC
Header/title color: #EAEAFC
Highlighted item color: #FCFCF2
