Please note that we currently do not have those different colors. We always display a red clock. I came up with that 
idea because some of our editors work a lot with scheduled elements and pages and asked more than once why element X is 
invisible while element Y is displayed. This is why I consider the different colors helpful.

For the meaning of the colors: basically red means the same like hidden, telling an editor who wants to set a link to a 
page or CE: No point to link to me, I am not visible anyway. The green clock with the green background tells us: I am 
visible, you can link to me, but be aware that I will only be there for some time. And the light green clock (colors can 
be discussed) tells us: You can link to me, but the link will only be valid in the future. This is what we want to see 
at a glance, further information can be gained by hovering over the icon.

My 5 cents, Uschi
