About a month or so ago I picked up Carpe Diem from Ravensburger. I really like the game, but I hate some of the production choices for coloring that ended up in this game (I have similar complains with Castles of Burgundy). I realize I'm getting older, and my eyes aren't as good as they used to be, but the structure tiles, there are two specific types that you need to separate from each other and you differentiate them by the color on the back of the tile. One set is green...the other is a slightly darker green. It's tough to tell them apart, especially if the lighting isn't great. I have an easy fix in that I can take a sharpie to the backs of the dark green tiles and put a better mark on them, but still...bad color choice, guys.
Castles of burgundy has a similar problem with its color choices for its tiles. Some of the tiles are different shades of green, and it's tough to differentiate them without taking a closer look.
That said I really like both games, just wishing some of the graphic design had been a bit better.
