the benefit of blue resistors or non brown resistors is that natural over heating deformation is brown and char is black, these colors stand out on blue, so a quick visual inspection may detect problems
however, there are better colors for this possibly, White resistors?
if you notice, fuses are often light green (through hole littlefuse), not sure if this is done for this reason to identify burn. The problem with white might be false positives from flux and dust contamination, they will show everything.
I assume you like the really old brown ones (true cylinder shape), not the tan ones, those will stand out better
low level/hunch/probability based analysis usually leads me to believe the tan resistors are 5% carbon film, but this is not always the case.
