In general, dark metallic grey is my favourite at the moment.
In general, I like black, but it’s impossible to keep nice. Its not just hard to keep clean, as soon as you start to clean it there’s swirls and minor scratches, chips etc.
In general I love silver. Easiest colour to look after and I like the fact that it looks almost unpainted, i.e. it’s just a nicely buffed piece of steel/aluminium.
The reason I’ve wrote “in general” thrice is because different cars really do suit different vehicles. For example my most recent car (Sportage GTLS) has lots of gloss black features which imo look really good. Therefore black looked awful as all the great gloss black features got lost. Dark grey (Penta Metal) looked great in some lighting conditions, but in others it looked quite dull. Silver (Lunar Silver) had a similar issue as the Penta Metal in that it looked great in some light, but not others.
I ended up choosing Flame Blue, which isn’t one of my usual colour choices, but it contrasted against the gloss black features and looked great in all lighting conditions.
My main take away was, especially with KIA’s colours, go see all the colour options in person, even if it involves trips to many different dealerships.
