There are three main theme colours to choose from – Red, Green and Blue. Each theme has 6 shades which can be used for backgrounds and other elements. Each theme also has Black, White & Grey.
Whilst it is possible to use combinations of colours on a single site, this is discouraged.
It is advisable that you use black or white for text. Shades with the suffix 400, 500 or 600 should use white text.
Theme options are set on the main menu. Accent and Navigation background colours can also be set.
