How to Change the Look of Your SharePoint Site (Themes, Colors & Fonts)

To change the look of your SharePoint site, click the Settings gear icon > Change the look > Theme. Select from default themes (Blue, Orange, Red, Purple, Green, Gray, Dark Yellow, Dark Blue) or supplementary themes (Gold, Teal, Indigo, Plum, and others). To customize colors, select a theme then click Customize, choose your main color and accent color, and click Save. For classic SharePoint sites, go to Settings > Change the look > View classic settings to also change fonts, background images, and site layout. Changes apply instantly and can be previewed before saving.  

SharePoint site owners can now apply custom styles and colors to sites and thus making it easier to define and manage themes across site collections. Customize the look of your SharePoint site to reflect your brand's value. The options available to a site owner depends on the version of SharePoint being used by him/her..
