That's some word salad but let me make things clear,

All intersections have signs indicating priority.

All intersections have road markings indicating right of way.

All intersections have a level change indicating priority. Either you bump up to pedestrians, which also reduces your speed. Or pedestrians step down to asphalt.

All intersections have/dont have color change to indicate right of way.

All intersections have/dont have pavement type indicating right of way (usually bricks for street or pedestrians, black asphalt for roads, red asphalt for cyclists.)

Although you could probaly find some rulebreakers in there, its universally accepted as such.
