Corolla gli 2015 plugs condition

Anyone can tell me what's wrong with the air fuel mixture these plugs always comes like this they supposed to be orangish or redish in color and I don't think that these plugs showing IDEAL air fuel mixture.

I have OBD II device connected that was showing fuel trims in negative 5 to negative 9 on Idle position and reading was in positive while doing a ride.

Anyone want to see OBD II stats should tell me what reading you want to see as there are many parameters .

Ok. But I want to share that I went on long drive and after 1hr 20 min of drive I started to face pick Issue on light throttle means car was struggling to accelerate in order to make it accelerate I have to fully push down accelerator pedal and car responded in that manner otherwise It wasted alot of fuel during this situation.

maybe the AFR is a bit too lean, u can check byt attaching an OBD device to check fuel trims etc

Should I checked for vacuum leak test because this also seems lean to me as center electrode is too much clean that shouldn’t be on optimal fuel burning there should be traces of carbon.
One thing more to ask do poor fuel injector seals lead to lean mixture as I have check yesterday that fuel injector seal were hard and stuck to injector port and injectors we’re sitting loose on holes with seals on.
