Hi, JJ-
The EVENTS module sets its own colors by use of "themes". You can change the current theme by selecting a different one under the EVENTS module SETTINGS:
SETTINGS->EVENT MODULE SETTINGS->GENERAL SETTINGS->THEME/SKIN
There are a few options already there. If you want to define your own EVENTS skin with your own colors, create a new folder within the "Themes" folder in the Events module folder and place a new CSS file within the folder with the same name as the folder.
Example:
Let's say you want to create a new theme called "JJ". First, create folder "JJ":
(your DNN root folder)\DesktopModules\Events\Themes\JJ
Now copy the existing "Gray.CSS" file from the "Gray" folder (located within the "Themes" folder) and place the copy into folder "JJ". Also copy over the image file "gradient_Gray.jpg". Rename "Gray.CSS" to "JJ.CSS" to end up with the following:
(your DNN root folder)\DesktopModules\Events\Themes\JJ\JJ.CSS
(your DNN root folder)\DesktopModules\Events\Themes\JJ\gradient_Gray.jpg
To change colors, simply edit the style definitions in "JJ.CSS" as desired. The image file is used as a background image for the EventTitle and WeekTitle CSS classes.
The new "JJ" theme should automatically appear as an option the next time you open the SETTINGS page for an EVENTS module.
Cheers!
