Well, to be fair, comparatively few black tomatoes are still "black" once they are actually chunked up. They tend to be dark red/pink with greenish skins/streaks And the "blue" ones are only "blue" on the skins; inside they're red or green. Pureed, or made into chunks, most are more or less the same color red wine is.
Of course there ARE some exceptions to the rule. One of the few "black" tomatoes I actively HATE is Purple Calabash. Part of the reason is that I just plain and simply don't like the flavor, but another big part is that I could never get used to eating a tomato which, to me, is more or less the color of a bruise.
There is a pretty good chance I will be making a LARGE tomato seed order soon. Probably mostly to the Secret Seed Cartel. I just found out about the site. They seem to have a lot of green when ripe tomatoes and I am a sucker for those. I keep continuing in my quest to have seed for every kind of green tomato there is despite the fact that
1. It's impossible, given how many new tomato strains are found/developed every year.
2. I already HAVE enough tomato seed to last me until the end of the NEXT millennium (there's so much I need a little file cabinet to keep all the packets)
3. with my space and conditions, the absolute maximum number of tomato plants I can have in a year is about seven (so ONE seed packet lasts me several years)
4. Most tomatoes don't really do so well for me. With no cold frame (or place to put one) and a grow lite array that really doesn't work that well, direct seeding is pretty much my only option (any seeds started indoors get so leggy no matter what I do they collapse and die as soon as they are taken outside) so my plants wind up so far behind that most don't make their first flowers until it's pretty much the end of the tomato season. Even when I DO get one to grow (say by using a pre started heirloom plant) most tomatoes tend to go into immediate death mode for me. They flower, make one tiny (and I mean tiny) tomato (if that) and then keel over. This seems to happen with pretty much any tomato above cherry sized (the cherry's don't make the number of fruits they are supposed to, but at least there are usually more than one of them, and they are normal sized with normal seeds (a lot of the tiny ones are all aborted inside) The last "reasonable" crop I got was from the near wild Ramito Dulce's I grew three or four years ago, and I HATED their flavor (I was ok with the Ramito Dorado's, but there were a lot less of them)
5. That "seven plants max" only applies if Tomatoes are ALL I grow on the patio. Every time I need a pot for something else, that's one fewer max tomato plants. And since by now pretty much EVERYTHING needs to be put in pots on the patio to keep it from being destroyed by now, most years I set out NO tomatoes. That probably includes this year as well; I need the spaces for the barley, the wheat (both of which will at least grow) the beans (while I try and figure out which ones will) and so on. With all that, the tomatoes (which I can pick up at the Farmers market (and will have to even if I DO grow any) don't rank high.
