Due to the overwhelming demand that the e2 jukka theme is "too bright", we now have a more relaxed color scheme for the jukka theme. If you go to your preferences, you will notice that you can now select the e2 jukka theme dim settings
from the theme selector.
You may need to do a SHIFT-reload on your browser to flush the old CSS styles for the new settings to take effect. Also note that some of the new colors (the background in particular) are not web safe. So, if you are using a 256 color display, it may not look right.
