I wondered the same thing. Is the color switchable?

 

I can't say this as "gospel" but....
Front turn and corner marker lights are to be amber. Whether by lens color or by bulb color in the USA. Lights off a white lens would look white, and with light on would show amber from a colored bulb.

 

We're talking about the light surrounding the headlights. Some Telluride's have amber, some have white (white when lit, not just when off).

 

According to post #3 over here, SX has amber, the rest have white:

Orange Daytime Running Lights

According to all the press photos, the daytime running lights that come on the Telluride are orange / amber. However, seeing the pictures of the Tellurides reaching the dealership, the daytime running lights are white. To me, the orange daytime running lights were part of what makes it cool...

From Kia's website:

Daytime Running Light (DRL), LED
"A streak of crisp lighting to identify the position of your Telluride on the road. Models with LED headlights feature a unique Amber color."

EX models have optional LED headlights and SX is standard

 

the SX and above comes with Amber DRLs. Everything below the SX trim comes with the white DRLs.
