Mine look the same. I think it is normal for the variety. They look very healthy to me. Beautiful color.

I got the same thing on mine

That colour is a pigment called anthocyanin, commonly found in dark blue or purple fruits, vegetables and plants. The stems, especially around branch and leaf nodes, often seem to produce it, particularly in seedlings. I believe the leaves will also exhibit it under higher light intensity, perhaps as a defense mechanism. I often see it on the edges of the cotyledon. For identical growing conditions, different varieties of pepper will show differing levels of it in my experience.

Perhaps of interest: Anthocyanin - Wikipedia - Anthocyanins have an antioxidant role in plants against reactive oxygen species caused by abiotic stresses, such as overexposure to ultraviolet light and extreme temperatures.

this is an old thread, but im gonna put this here for anyone who stumbles apon this in the future. It is entirely normal. The amount and location of the colorization depends on the climate you choose to grow your plant. I have some indoor peppers, and they have slight purple on the joints between the branches and the main stem.

So, my bell pepper plants did this and then some! I need to find someone who knows something about this to give me some advice! So my plants were definitely put under some stress, I kept them in gallon pots for a few month while we were waiting on the closing of our new home. They didn't like it at all, the pots got hot, if I put them in the sun for more than a few minutes they'd wilt, even when moist. They probably got knocked over and scuffed in the move as well. Now that they're in the ground, they're making peppers and they all have the purple stems and crooks but check out what this one plant is producing!!! The other peppers are normal green!

Taken September 1st!!

Taken today, September 5th!

What is UP with that?!? I really want to know if I can eat it! Anyone have any thoughts or ideas on this?!

Which pepper variety are you growing ... some ripen purple. I grew one called something like Purple Beauty. It came out a touch more royal purple, but nearly black is normal for some varieties. Purple Beauty was very tart, so it wasn't our favorite, though one of my guinea pigs thought it was the best ever; it was nicely thin-skinned.

Purple is absolutely an edible bell pepper color. "Normal green" is usually a less ripe state of a pepper that grew to size but didn't yet turn red, yellow, orange ... or purple.

They should all be just regular bell peppers from the same seed packet. I'm not sure if it was purple when it was tiny or not and the plant has not started another fruit yet, so I can't tell if it's the plant itself or just a freak occurrence. The others on different plants are about the same size and age as this guy though and they are not ripening at all yet!

Some seed packets come with mixed colors, like these ones from Burpee:

Almost all peppers will start out green, and different peppers do ripen at different rates. I've had some that seem to take forever to turn and then change rapidly (PeppiGrande) and others that start changing earlier but do so much more gradually (Gold Standard).

It's also possible that you've got a natural mutation or a rogue seed of the wrong color in your pack, but it would be less common. I can't say I recall how quick Purple Beauty was in comparison to other varieties.

So,you don't think it could be from the plants response to stress? Like the stem/crooks turning purple? Should I eat it?

Anthocyanin pigmentation accounts for the colors of peppers, and that compound can end up not just in the fruit, but in the leaves and stems as well. They do relate to stress tolerance, so a stressed pepper plant my have funny stem colors. Nothing to do with edibility.
