Well, I have a bunch of lower-end black fans, some of them quite old, from before transparent cases were a thing. They're actually pretty much gray if I don't wipe them off.
Noctua's signature... brown-orange? Whatever that color is, it has the same issue. The blades are basically gray if I don't wipe them.
Haven't seen anybody start a gray craze, though. Though I have a grayish motorbike that also shows dust and dirt like nobody's business (it's a bike I use strictly on paved roads).
Silver is the ideal color for hiding dirt. I had a silver car once. Unless you drove it down a dirt road during a rainstorm, you basically never had to wash it.
They never did catch you riding dirty.
I don't know why someone downvoted you. For an offtopic joke, this one is pretty good.
Noctua also makes silver fans
They have matte grey, but silver metallic on cars is pretty different. Think of the brushed appearance of a Tesla Cybertruck or a DeLorean.
I found that having a positive pressure setup with an intake filter practically eliminated the dust buildup on my fans.
If it were about performance and not marketing, they'd try to optimize for resistance to dust adhesion and resource consumption: energy, cost, durability, etc.
What makes you think they don't?
Okay, I'll bite.
What is it you think they're doing wrong?
Does another vendor satisfy your criticisms?
Why do you think they don't optimize for things like performance when they often win performance competitions against other vendors for both sound mitigation and airflow?
Do you know they have a specific high efficiency line?
Have you ever had a noctua fan fail where you think another vendor fan would not have?
