What car is it? It's usualy an antipollution thingie that you don't care about, the car will work anyway.
Basic rule : if it's important, it's red, if not : orange.
Oil pressure would be pic rel but red.
Even then I bet you "antipollution goy system" still works fine and a $0.50 sensor is doing shit (which could be fixed with a simple reset like for the tires pressure thingie doing shit when it's cold or hot, read the manual).
tl;dr not red (WHILE DRIVING) = dun care
fuck computers
