The bottom of your brown colour has a border along it, you would need to use an image editor to remove that border unless you do want it to have a line along the middle.
Look in colours for:
Code: Select all
.headerbar {
background-color:
background-image:
With the above border still there, the background colour would be: #60437b
If you remove the border, the background colour would be: #8c3363
Boom.
