Pretty sure the OP is a new player and doesn't have a sugar daddy 50 to twink his character out too.
I do not have a level 50 "sugar daddy". I did great at level 15 (had issues that Admiral Akbar type mini-boss) and got beaten by the end boss Jedi. Other than that I had no issues.
Update: I reached level 16 and the Black Talon quest is still Green. It looks like quests turn Gray when the character is 7 or more levels higher than the quest.
