Just double-checked. It doesn't appear to have the Commodore brown.  My comparison was the screenshot of the BIT-C-128 VideoDac at https://www.bit-c128.com/

Oh, it's interesting!  I wonder how well it does with Commodore brown.

Commodore 128 C128 16-Color, 80-Column RGBi 15Khz RGB to VGA Adapter

PRICE:
17€ --> 8 colors
19€ --> 16 colors
36€ --> 16 colors + VLR
https://www.ebay.it/itm/376241376516

NEW C128 RGBi adapter to VGA!

Connect your C128 RGBi port to VGA monitor (15KHz horizontal freq. compatible!)

The anchoring screws for the C128 are present, as well as those for screwing for the VGA cable!

Just simply select the option that you want:

TYPE 1 --> 8-color 80-Column RGB

This adapter version is used to connect the rear 9-pin RGBI port on the Commodore 128 to a 15-pin VGA cable which then connects to a 15-kHz capable VGA monitor.
This gives you 8-color output and 80-Columns (double the 40-columns of the VIC-II chip) of text using the VDC Chip inside the 128.

TYPE 2 --> 16-color 80-Column RGB
This adapter version is used to connect the rear 9-pin RGBI port on the Commodore 128 to a 15-pin VGA cable which then connects to a 15-kHz capable VGA monitor.
This gives you 16-color output and 80-Columns (double the 40-columns of the VIC-II chip) of text using the VDC Chip inside the 128.

TYPE 3 --> 16-color 80-Column RGB + VLR (with USB power cable 1mt)
This adapter version is used to connect the rear 9-pin RGBI port on the Commodore 128 to a 15-pin VGA cable which then connects to a 15-kHz capable VGA monitor.This gives you 16-color output and 80-Columns with a PERFECT IMAGE because is equipped with VLR!
It is equipped internally with active VLR circuit. Power cable cord is included (USB connector 1mt) and you have to connect to standard AC/DC adapter (like smartphone)
This gives you 16-color output and 80-Columns with a PERFECT IMAGE because is equipped with VLR!
These vertical bars are visible especially in VGA mode on the first ASSY versions of the 128. The advice is that if you have already connected your c128 in 80 columns and you have these vertical bars on the VGA monitor then with this version you will notice an incredible improvement

PLEASE REMEMBER THAT:

This ADAPTER requires a VGA monitor that can sync to a 15-kHz signal. Normally, VGA uses a horizontal frequency of 31.5kHz. But, the Commodore 128 basically outputs a CGA signal which is a 15-kHz digital RGBI standard. It's this standard of the Commodore 128!
In any case there are some modern VGA monitors capable of displaying 15-kHz (Acer, Dell, Asus, BenQ, etc. etc).

I recall he had retired due to problems with his hands, but upon following the link, I read that he had been caring his wife who passed last year.  I didn't know any of that.  I am sorry to read of his loss.
