Need Some Images And Help With Two Wurttemberg Stamps

Does anyone have side-by-side images of Wurttemberg Scott #O27 (rose lake) and O28 (violet brown)?

The Michel numbers are 118 (karmin bis magenta) and 154 (dunkelbraunlichlila).

The images I'm finding online are not of the two side by side, and many sellers appear to be misidentifying them in favor of the higher value stamp; there's little consistency. The value difference between the two is considerable.

Thank you.

Here they are

Thank you. I don't see how Scott gets "brown" as any part of that right stamp's color...

I have O28 but not O27, so cannot post a comparison, but my O28 is a much browner shade than the stamp pictured above. I will try and scan it later.

More Brown -lilac in this example:
