Some of you folk are either color blind or are watching on an old cathode ray tube set. Others are getting down to reasonable issues.
I've got my problems, too. I'm not so good at picking out green jersey Sagan from all the other green jerseys, and I was downright confused on a recent race (TdS?) when the leader jersey was red and sponsored by Lotto, and looked too much like all the other Lotto jerseys.
The TdF Tinkoff kit is not quite Farnessi-Vini gaudy, but it is distinct from their team kit earlier in the year and from the maillot jaune.
There are plenty of mostly black kit teams around now (OPQS, Giant-Shimano, Trek, and Sky to a lesser degree). Fortunately their geometric differences are more blatant than those within the green brigade (Cannondale, Belkin, and semi Europcar).
There are only so many colors to go around. It's a different place without a little orange.
