To begin, yes barbarus majors derivative from bicoloured queens typically exhibit bicolouration with the reds becoming more vivid relative to the size of worker, though this is usually exclusive to the head of the major. There are a few pics of one of my barbarus majors on my journal here on fc for reference, the colony she is from also possesses a ‘fire red’ queen, from Antsrus, ironically.
This brings me to my second point, if you want to buy from a messor queen from antsrus, don’t get the fire red queen. The red coloration is barely visible on the thorax and is any good colour can only be achieved through photos with the super high saturation. Just stick with getting a bicoloured or redhead queen, it’s not worth the money otherwise.
Messor cephalotes only have one colour morph to my knowledge and is a reddish black colour, and as much of a great species they are to keep, prices usually exceed £400 for a single queen (I’m assuming you’re in the uk) and are super hard to find on the market unless you contact a private supplier. Not to mention they grow super slow, compared to most messor species.
If you are looking for a larger species of messor for a bit cheaper, I’d suggest looking up messor arenarius, they are still a bit expensive around 180-250 quid per colony with a few workers, but the queens still reach 21mm and majors typically get to 17-18mm in length, being the second largest species in the messor genus. the colonies grow slow and the only colour variant is a shiny black (they can appear slightly iridescent in the right light). But they do at least guarantee size if that’s what you’re after.
Edit:didn’t realize how old this post was, please excuse my ignorance.
