Actually, only two colors found on 1867-68; claret and rose brown. These two of yours are medium claret (left) and pale rose brown (right).
Claret has a wide range of hues, hard to quantify at times. It's one of my personal favorites.
Pale rose brown is closer to a light brown. The scan in this case is set too bright and so you can't see the brown color properly.
It should be noted that "rose" is actually a darker shade. Below is a swatch of china rose. This isn't the actual color, but gives you an idea of what rose looks like.
