Default Reading Spark Plugs

well im not sure where this post should go. but these came out of my early 96 EJ20G. i know a good plug should be kinda brownish, but these plugs are more of a red.

this one is cyl #4. in order from best to worse it was 3-1-2-4 so both left side plugs were worse than the right side plugs...

probably due to the fuel rails being in series (stock retarded setup) leaning out the left side.

i wouldnt worry, dosnt look like any detonation or preignition.
