Not to the best of my knowledge. I think the confusion...
... lies in the fact that (1) many people (myself included) use "pink gold" and "rose gold" interchangeably even though they're different, and (2) these watch cases (like yellow gold watch cases) develop some (variable) patina over time. I think Lange has always used "pink gold." Here's what Lange says on their website:
The reddish tone of the gold comes from copper. This fine gold is soft and corrosion-resistant and produces a precious metal that is high-grade, exquisite and highly popular in watchmaking. The colour nuances, depending on the copper content, range from soft rose to powerful dark red. At Lange, pink gold is used with 205 parts copper to 45 parts silver. This makes for a purity of 18 carats (750 ppt).
Is the rose/pink gold and gray dial the same on these watches?
Obviously the perpetual vs timezone are completely different watches. But is the case metal the same material and color? Is the gray dial color and material the same? The pictures were taken by different people at different times in different lighting but...
Ok so Lange didn’t switch from Pink gold from Rose gold at some point
The case metals from new and old models are the same?

I would not base my conclusion on your picture taken by different people and different setting. Most phone picture will rarely capture properly the colors unless you arrange it in post
Most likely they should be very similar. Cheers!
Pink and Rose Gold
To expand on what CR mentioned, technically rose gold and pink gold are not the same, though many people (myself included) often use the terms (as well as "red" gold) interchangeably. All three are 75% gold; red gold then has 25% Cu, while rose is 22.5% C...
In German they use word "Rotgold"
It means, red gold (check the same page mentioned by CR, but change language to Deutsch) Why it is just pink gold for English version - no idea )) WBR Serge
Rotgold
Yes, this has always mystified me. For "masculine-oriented" models I think that "red gold" sounds more appealing than "pink gold" and I have always used "red gold" when mentioning the metal in English as it is the direct translation of what Lange says in ...
