I get what ljn21 is saying. I have a 2017 Ex, but am guessing nothing has changed with the lighting thru the 2020 models. The ambient lighting is an interesting feature, but I'm not sure Ford didn't somewhat miss the boat with getting it right. Some observations:
The lights referred to in this thread are what control the sunroof (slide, tilt, shade). They are all what I'd consider a light blue color and they match all the other non ambient lighting in the cab. Examples that match are all the window controls, door locks, mirror adjustments and the like. I'm not an artist, so color coordination doesn't make that much difference to me, but mixing a bunch of essentially blue light that can't be changed with the colors available from the palette for ambient lighting, well, I'm guessing some don't go with blue
To make matters worse, the colors described on the palette don't really match what I'd have in mind for the color description. Take green as an example. When selected, it looks more yellow than anything to me. The "pink" that ljn21 referred to is actually called purple on the palette. So that's where I think Ford might have missed the 100% cool factor with the ambient lighting. I'd give it a solid 85% though. You could take this even further by looking at ALL the lighting colors and asking if they need to be the color they are. Take for example, the drive selector knob just aft of the gear shift (probably have those terms wrong, sorry...) The light in it to show what mode you're in appears to be always red. Why red? Red is usually reserved for warning lights that really need to be paid attention to. Same for the center console yellow-ish lights that indicate ON. Yellow is usually reserved for caution lights, but that is some deeper level stuff that quite frankly would be cost prohibitive to do differently for the overwhelming majority who don't notice or care. One last plug I'll mention in case any of the Ford design guys are reading, is how the touchscreen controls display things that are on versus off. The subject is lengthy, but suffice it to say most displays when first used are ambiguous. Does a dark blue box when the others around it are white indicate that feature is on or off? Then there is the use of the words on and off; does that indicate the current state of the equipment or does it indicate what will happen when you touch the button. The auto industry could take some notes, both good and bad, from the aviation people; e.g. 737 Max "problems". You don't want the folks up front pushing the wrong button at the wrong time, but I digress. Sorry
In terms of the dimming feature, it feels like another bit of a miss on design with the dimming push button at the upper right corner of the headlight control. That dimmer only appears to dim the main instrument cluster and the lighting on what I'd call the manual backup controls in the center console underneath the infotainment screen. The screen does auto dim if selected, but really just swaps to a different "dark" theme where they try to eliminate white by substituting black. Would have been nice to have the dim button actually dim ALL the interior lighting, not just certain ones and without rooting through the general menu options on the main screen.
IMO there is probably too much light pollution inside the cab due to having the lights up and not being able to dim things as low as they should be to aid in visual lookout. The same concept we all have experienced when you turn the map light(s) on at night which results in reduced ability to see outside through the reflections.
I'll summarize by saying I do really like the interior look and feel of my Explorer but there is room for improvement. I chuckle though when I reference the things we "complain" about when I think about my Dad's 23 model T.
Happy 2020 everyone!!
