I know it is too colorful XD But colors are customizable!
Also about this theme, you have 8 sidebar images and 8 links on those, you can see how it works on the preview, I suggest you to upload all of 8 images and not any thing less than that. ( Images’ size should be 300px/300px !!! ) Also perma colors ( notes, date and reblog ) are connected to navi colors, so keep that in mind while customizing!
