Each camera brand is different, but you seem to have the basics about right for Canon. The color of the adapter is irrelevant, it either has a chip that allows focus confirmation or it doesn't. The chips vary in whether they can be programmed or not, and how complex it is to do. It's useful if each chip / adapter is dedicated to a specific lens, but not for an adapter used with different lenses in my experience.
I think all that is needed is the simplest adapter, without chips, assuming you are using an all manual lens, as am I. Maybe if I was using an automatic lens of another brand the chipped adapter (for autofocus confirmation) would work, and maybe the programmable one is for providing communication with all of an automatic len's functions. Don't really know, as every lens I've used has been all manual. As for color, I just commented that the programmable adapters are thicker and have shiney metal. I guess you have to get something for the extra money. They were all pretty cheap tho, but the cheapest unchipped one would probably have been fine for me.

It's not the adapter but the chip (for Canon) that makes the difference. Focus confirmation is very useful. The lenses may be manual - FL / FD /FDn - or Helios, Contax, Nikon, or whatever - but the adapters have to adjust for the flange focal distance. I may have done a lot more of this than you have, but the color of the adapter is not relevant.

You never heard me say the color was relevant. It was a comment, no more. Thanks for the info on the A/F, I will always use a chipped one then.
