Roof Color Change in Rain (please see photos)

[sushixoxo]

Hi Guys--

I did a quick google search and understand the general principle of the glass roof and rear window changing color with rain and condensation due to the UV/IR reflective coating. However, all of the pictures I've seen are orange/red tint, somewhat of a gradient, and affect both the roof and rear window similarly. On my car it's a bright bumble bee yellow and is only on the top roof and not the rear window. My questions are:

1. Does my roof color change seem a little outside the bell curve? Do other people's roofs look like this? Does this mean my coating is defective?
   
   
2. If both the roof and rear window have the same treatment, then why does my rear window not change color as well?

1. it's fine.
2. they changed suppliers in late July/early Aug. Normal.

Ok-- thanks for the reply. The aesthetics are kind of ghastly, but glad it's not defective.

It's a dielectric stack coating and what you are seeing is a thin film coating effect. Will appear different colors in different light and angles. Only the top glass now.

My understanding is it completely blocks out UVA and UVB radiation so it is well worth it. I think the color looks cool when covered by rain drops.

It does block UV, but the color effect comes from the layer that blocks IR.

100% normal.

Here is my car in natural light:

Never knew they changed it. Glad I got mine before the change. I always dig seeing it when it’s wet.

I've seen my roof glass appear in different colors off and on.

This morning it was pretty cold out and it had rained overnight. The roof glass was more yellow and wish I had grabbed a photo. I remembered OP seeing your post with your bumblebee yellow color and it made me wonder if the outdoor temperature also determined the coloring. Today was definitely the coldest (guessing 30sF). But today was also a little after sunrise so maybe the amount of sunlight a factor. In any event love to see the color changes.

Leaving kind of early this cold a.m. With condesation on the car and roof. Saw this.

Also notice though as I repositioned the cellphone's camera that the coloring changed. Guess it depends on the angle of light instead.

Oh, interesting! Mine has a build date of November 18 (per window sticker) and it looks like it has the full treatment? (As shown by TT97.)
First post (I think?) Thanks for all the great info here! I will fill out sig later.

Whats your VIN per chance? Even though your November build date is more telling. I bet they simply found some excess stock somewhere.....

i believe mine is the back window as well, 12/18 build.

 

[Stellavator]

Interesting. I wonder if the non-refractive rear glass set-up was temporary? Maybe a supply issue, and now going back to original plans?

 

[Olds442]

actually nope, mine only has it over the driver and passenger, not the rear section. that just looks tinted black in comparison.

kinda bummed, i like it consistent across the entire top.

I have a Sept 2018 build date (picked up at end of month) and have the colored effect only on my driver glass portion. The rear glass is a black look. I do remember a thread on here a while back (several months now maybe) that discussed that Tesla was using 3 different glass manufacturers for their windows and each may have their own type of IR coating but that all windows did have it and that their coating gave different looks from the other.

Enjoy going out to my car during this time of year and seeing what the roof looks like. Today, lots of little colored gems.

Hi, I was thinking that might be a possibility. When I ordered mine, there were two in stock with my spec, so I took the older one. Maybe it was much older?? Now I'm worried, why was this one still sitting around in all the frenzy? LOL...
VIN 146XXX (Did I do that right? I'm such a n00b! Not to msg boards, but just to Tesla.)
Thanks.

Took delivery on 12/22 with VIN 172XXX, and mine also goes 1/2 way down the rear window.
