Expedition Color Cards explained?

[CHARLIE79]

After finishing 100% of the story, I started playing the other modes. I DONT UNDERSTAND WELL how the cards work in terms of color: Bronze, Silver, Gold, Black and Blue.

 

Seems Gold cards and permanent, but please can someone explain me what are the differences of the Black and Blue cards???

 

Even if the game came out 1 year ago, I cant find anything on the net to explain that and my digital version does not have a digital manual or something to explain it.

Hi everyone, I am writing here since I am looking for explanations too before going deep into Score Attacks and DLC Endurance solo and Coop. 

1. How do we know a card can be used several times or not? (It seems it can only takes 2 values: 1 or +infinity)
2. Some cards can be sold, others not. Is there a link with the number of use? (see question 1)
3. Does someone see the difference of colors between black, gold, brown, blue, etc. 

Thank for anything which can help!

After searching calmly on this awesome website (and getting annoyed inside the game), useful info about cards are furnished here:

and inside the guide for DLC Endurance:
