The colour changing is totally normal. It’s just like your normal skin changing colour when you get cold or hot. Some people go red at the drop of a hat, others don’t. Some people’s skin goes purple and their veins become very obvious when they’re cold, others don’t.

The scars that I have that haven’t faded change colour as well. It’s been a while so all of the small ones are now white, but before they faded, after showers they would look kind angry even though they felt fine, and the few bigger ones I have that are not faded, also change colour, sometimes turn the deep purple you describe. It’s nothing to worry about.

I don’t have much advice on the itching though, my few bigger ones do itch occasionally though but not all the time. (Just to clarify, talking about fully healed tissue, not scabs or wounds).
