My crop didn't do well so purchased an extra batch. Many seedlings were in a single 8cm pot. Managed to seperate without much damage to roots
Is the colouration normal as its not what I would expect and when should I see next set of buds appear.

Hmm…. The brown ones are toast. The green ones seem ok.

Likely you’ll want to get a lower bend in these trunks next spring.

My JBP seedlings all went purple a lot of winters because I was overwatering them. It became more evident when the soil froze and formed huge lumps of ice, shifting everything.
After a couple winters they petered out. Because my overwatering was chronic in the rest of the year too.

All this will depend where in the world you are and when the repotting was done. Very different responses to repotting this time of year in Southern hemisphere compared to Northern. Also different response in colder climates compared to tropical areas.
When buds will appear also highly tied to location and local climate.
Some repots have temporary change but then recover, hence the need to know when the repotting was done before offering useful advice.

Repotting was done about 5 weeks ago, updated location (Wales, UK)

Petered out as in died?

Not the best time to be messing with roots, probably could have left them until spring before separating.

I typically give my seedlings at least one or two years before disturbing them.

The grower I got them from had 12 or so seedlings in an 8cm pot. There was little choice about repotting.

Are you asking for help and advice as a newbie then telling a very experienced grower his advice is wrong?
Those seedlings were at or very close to end of growing season. They could have quite easily stayed together in the containers until Spring optimum repotting season. I've regularly had pine seedlings crowded in seed trays for up to 5 years. They do not grow as big as individual pots but they certainly don't die either, provided care is adequate. From the info given, I'd also say these seedlings could have waited until Spring and saved all this anxiety about whether they will live or not. however, that option is now closed so we need to deal with what you have.

Even given the less than optimum timing, seedlings are very resilient so I'd be reasonably confident most will survive the transplant. We can see that some are likely dying and a few more are likely to follow but enough are still green and healthy looking to be optimistic that you'll still have some alive next season.
One of the problems with pines is that they are often slow to recover and slow to show trauma. It can be several months before some decide whether they will live or not.

I felt they were overcrowded and could suffer and the grower also said to repot upon receipt. Once out of pot there was almost no soil, all root. I didnt say newbie but im not years into growing/propgating.
"These were sown this year and are now prepping for their winter slumber. Plants are 2 - 3" tall.

Saplings are in pots. I recommend that they are separated into individual pots upon receipt."

I do defer to others more experienced though and was only stating what I knew. Appreciate all guidance.
My main query was about the colour difference, why some had gone purple a sits not something I was expecting to see

Interesting that the supplier has no seasonal qualification on that recommendation. My experience is separating seedlings in Spring and early Summer no problem but closer to Winter and success declines a bit which I think you have now experienced. Maybe Yorkshire is different and pine seedlings can be potted on all year round? Maybe the supplier did not want to confuse the issue or could not be bothered with qualifying that blanket statement?
In any case, I think you'll still have plenty of these left to play with next season.

The purple colour is not unusual but I normally see that in winter or when under some other stress which could be starvation, cold, etc. Your seedlings are under stress from the repot so the colour change is likely a result of that. Maybe those purple ones had a bit more root removed?
The brown or black ones are most likely dead.

New buds should appear through Winter, ready to open in Spring

Yorkshire is a bit colder but ppl there dont seem to feel it. Not a different climate though.
Thanks for clearing up about the colour for me it makes sense now
