Good News: there’s currently an Amazon Basics filament in just the right color tone available: Amazon Basics Light Grey PLA GTIN 008400958003 .
According to a calibrated color reader output the color tone of the filament (#C4C7C1) is very close to the original of the Bambu (#C4C3C5).
Bought it yesterday and printed an additional spool holder for the A1:
Thanks… Now if I could only find something in the U.S. similar. 
Hey,
Just wanted to add another option (primarily for DE/AT/Europe):
3DJAKE mattePLA Light Grey, 1,75 mm / 1000 g (“house brand” filament of online shop “3Djake”, EAN: 9010707007265)
I was about to get the PrimaValue PLA+ based on the posts in this thread but the 3DJAKE filament was on sale for 13,99€ during black friday so I gave it a shot.
The spool I received today is a very good match for the light enclosure parts of the A1. Depending on how light hits the structure of the print, the color may seem a nuance lighter after printing. But in combination with the matte finish it’s a close enough for the girls I date.
(I am unable to post media or links at this time. Maybe I can add a photo later)
Bambu PLA light grey (101104) is a perfect match
Do you have a picture of this color next to the printer?
I put the color sample next to it. Perfect match
Can you show a picture? I’m pretty sure I tried Bambu light grey and it wasn’t a match. Of course, it could have been the dark gray.
I do but apparently I can’t attach it here

Hi, could you also make readout of the darkgray part?
Thanks for the tip. It’s near perfect.
