Slashes on the head of the bolt are for SAE(american) bolts.
Metric bolts will have a number to show the grade.
The thread pitch has nothing to do with its grade. You can find both fine and standard pitch bolts in most grades.
The color of a bolt may just be the coating applied to the bolt.
You can find some bolts that are colored to denote a grade(I use one local supplier that has all its Grade 8 bolts colored blue)
