Bought these without reading the dwarf bit, anything dwarf is slug food normally but these seem to have done ok. Nice purple flowers and a purple tint to the leaves but the beans are green 

Do they turn purple when fully ripe or are mine defective ?

[Kleftiwallah]

I think they are in the clear as far as the trade descriptions act goes,  after all, the flowers are purple.
      Our pods are megga purple from day one.     Cheers,   Tony.

They start green, go purple as they mature, then go green again when you cook them.

Sounds like a waste of time doesn't it!

But it is easy to see when they are ready to pick, and they show up well against the green leaves

As long as they will turn colour eventually.

Thats actually exactly why I bought them    Id have preferred climbing ones, "dwarf" is a long way away to spot green beans on a green plant !

Oh are the purple ones more slug resistant?
I have a whole row of Ferrari 'sticks'

Not sure. If you have slug problem probably best to use the lttle blue pellets or similar tbh 

[Lardman]

I think its probably a coincidence, I've not actually had much of a problem with slugs this year at all. 

Last year I tried Ferrari and Sonesta both ended up as slug food before I saw a single bean.

I've got climbing beans with purple flowers/pods, Blauhilde. No pods on it yet, though, just flowers.

My Purple Teepee have purple flowers and the beans are dark purple from the start. Shame they go green when cooked!!

[DD.]

I like Purple Teepees, you can see where the beans are!

[Beklet]

I have some of these, and now they've recovered from the blackfly, the flowers are purple and the pods almost black, they're dark purple when fully grown...dunno about cooking, haven't got round to that yet!

[GrannieAnnie]

I grew some purple ones last year and they were purple from the start.  did really well too.

If you steam rather than boil, they stay purplish!

[DD.]

When we steam, we get green veg & purple water!

[GrannieAnnie]

Oh!  Mine went a dullish purple, with purple water!
