I'm planning to do something with a table or so at the Arrival Center where viewers can see which "button color" means what.


Image Description
Splice Grey
If you choose two professions to combine at the Arrival Center and this button shows up, the two professions do not combine. Though, the formula could result in a secret gene, which has to be unlocked first by completing particular missions at the Utopia HQ.
Splice Orange
When this button appears, the two professions you chose have are a combination, but you have already spliced/discovered it. Pressing the button anyway results in a (wished or unwished) clone with the spliced job. The splicing when pressed this button takes 10 seconds.
Splice Green
When you see a green button, you have found a secret combination which you have unlocked by completing a particular Mission.
Splice Blue
When you see this blue button appear, you have found a special gene that can be spliced, but isn't highlighted in the Arrival Center. The special gene is a kind of bonus gene that can only be discovered by experimenting a lot at the Arrival Center.
Splice Under Construction
If you have spliced a profession and you see this sign next to the clone, you have to wait till that building has been built till you can employ the clone at that building. Note that if you don't employ a clone in the Arrival Center, it will block new incoming clones.

NOTE: Not all buttons are shown here.

After that, I still have plans to upload some of the building and profession images which have not been uploaded yet or which need to be improved (like building images with background texture)
