Technical white colour on spark plugs

[TONY55S]

Hi All,
Just bought a 2006 punto mk2b 1.2 8 valve.
It has 90,000 km
Just noticed last night when i checked the spark plugs that they are a
whitish colour,think they should be a tan colour.
Is this normal or is there something wrong.
Car drives with plenty of power.

White = lean conditions or has run hot at some point

Also some.fuels have additives which can cause a white plug as well

A plug and ht lead change as maintenance may help but not a guarentee

Leads do fail also over time
They gain resistancr affecting spark quality and forces coils to charge higher to provide spark which in turn could/maybe/possibility in long term of burning the ecu out
