Pearl, girlfriends... show me another one of these...

A notoriously difficult color to match on a partial re-paint. yes, I've spent 2 years of my young life doing color science

Uhh yeah.. I meant, uhh.. besides that one.

You're not kidding about a partial repaint, Nile. As you can see in the the pic, there's a part of the front bumper that is no longer flush and she's going into a body shop for that repair when she comes out of deep freeze in the spring.

Fortunately, the paint is good but I've had it in with a dealer, a local PCar garage and a specialty shop (for a potential front end wrap) who all sucked in their teeth when I even brought up the possibility of ever doing a respray for any part.

I mostly got back, "Yeah, good luck with that". I stopped bringing up "touch up paint" in conversations after several looks of sadness mixed w/ disbelief.

The issue with pearl paint is that it's extremely reflective and actually reflect differently than regular paint, i.e. more directionally. The first common production pearl cars, I believe Audi 5000 of 1983, or so, were a complete nightmare to touch up.

Human eye is such a weird tool... I used to make spectrophotometers for color matching for Sherwin Williams and learned how non-linear and illogical the eye really is compared to sensors. But even having said that, I really like pearl white cars.

Is that a question of context?

Say, like Deep Mind beating someone at GO while remaining horrifically inept (in our mind's eye) at parsing one color from another?

Kinda, sorta. It's a question of a tool specifically made for its purpose. In case of humans - to catch and discern a reflected (sun)light. The sensors in color matching spectrophotometers have to "average out" lighting conditions. For example, ours, in mid-1990s, had 7 different color LEDs shining light through 4 different filters and trying to average out the reflection, all in absence of unmetered real light coming from outside. The human eye, however, would look at something, figure out the "color" and as soon as the light conditions change even a little, it would say "no, that's a different color now". With reflective stuff, like pearlescent paints, that light condition change is pretty constant because the color is not just a pigment, but often contain some sort of reflective flake to bounce the light differently in different direction. So, you step sideways a foot and you get a different color.

I mean, all of this is similar to robotics (another industry I've spent time in as an engineer). Robotic arms are great, but none of them have dexterity of a simple human arm.

And one I haven't fannied about with

That looks amazing, but is the photo enhanced or does it look like that in person? If so, WOW!

Turquoise metallic is not a PTS color and it looks nothing like the car pictured above. Hold on a minute as I make my guards red look orange

tbf I did say the top photo had been fannied about. The second one is straight out of the camera.

I like the pink laces on the clown shoes.

Gotta have the talent to pull them off
