Just wanted to be sure I understand runes correctly. I'm posting 3 pictures.
Pic 1: Is this a possible rune or something thats just highly salvagable? Curious why it's purple because I get others just like it thats white? What should I do with it?

Pic 2: Again same question. Possible rune? Highly salvagable or is it purple this time because its special and requires blood Magic to use?

Pic 3: Ok fairly certain this IS a rune? If I understand it correctly buy an expert salvage kit and salvage this for a good chance at a rune?

I'm basically trying to understand the rhyme and reason to the purple and or how the equate to runes.
Thanks
