I've got an older metal box HDMI to AV adapter that's out of production that works better. Though my go-to is an HDMI to ATSC transmitter and a DTV converter box for my tube sets...It's expensive but gives me the best quality and aspect ratio control I've been able to get from HDMI sources.
This video gives an overview of that stuff. https://m.youtube.com/watch?v=hKjt3x4WtWU

but it's pretty clear that the HDMI to AV adapter is the source of the color problem, Timmy has the same as I had, looks the same, I spent over 2 hours screwing with it and color never worked on the stupid thing, so it was thrown in the garbage.
the review i left for it
VERY poor quality.
But that is not surprising for the amount spent on the unit, I was hoping it might work, but like many others who got it, I was disappointed.
I got this unit to try to convert HDMI to composite for a vintage TV, if you are expecting black and white only, then this may work for you, but if you want color, get something of better quality, because the colorburst freq this puts out is WAY OFF, meaning that any vintage equipment can't lock on meaning NO COLOR at all, or barberpoleing if it tries to lock in color.
The only way to get this to work correctly is to run it through a time base corrector to correct the colorburst phase errors and get TRUE NTSC color out of it, which makes getting the thing rather pointless.
Bottom line, get something better.
