your footwell lights look good - i added some to mine front and back
and a few other places
i don't have 'puddle lights' - got some bolt mount leds and plan to some day.....
i did put some bolt led lights on the bottom of my front doors - drilled a hole and tapped the courtesy light wires that are already inside the doors - the back doors don't have those lights and i'll have to get wires through those rubber boots in the hinge area - and that seems like real work so...

put some in the door openers inside the car - power is already there for the window and lock buttons so that is an easy one - you won't mistake it for a benz s class but for a 20 year old ford, not so bad
i played with rgb leds - i have that willow green interior too - thought maybe i'd power the leads to make it green but it looked funky - so i powered all 3 leads and made it white light - except for the one i mounted behind the ask tray - it had one of those blue/green/teal/seafoam/whatever gel covers on the bulb - that disintegrated - so i did the green for the ash tray (this is the full console ash tray - it has a little window to illuminate the recepticle - which is always dim so the color works) - so i think you are right - white works inside these green interiors
gonna put one at the top of the kleenex opening - no easy way to put one in the cupholders
love these led lights - cheap - very little power so you can tap these small wires without overloading them - lots of light - and easy to install
whooda thought ambient lighting in our 20 year old fords and the 5 year old fords go without...
