I usually use DaVinci or Premiere to do conforms but sometimes clients request I stay Avid only (sometimes effects don't transfer over which is a good reason to know it, too). I learned relinking the Avid way and can get consistent results with relinking colored/trimmed clips. I have relinked ProRes files without a problem. The problem occurred when I was delivered DPX files instead of ProRes. 

I conformed everything in Davinci, since I was unsure how Avid would handle DPX, and the color looked great. The editor had used an Avid stabilze filter which didn't transfer over and was hard to recreate in the timeframe available. I tried to AMA link to the 10bit DPX files for the specific shots that I needed but figured I'd link the whole thing to see if it worked. Everything was great except for the really dark, saturated colors and very blown out highlights. I'd really like to make it work (at least just to make it work) because It could be a time saver for certain projects.

Is there a color setting or step I'm missing? I tried all the display color spaces and project color spaces. I looked for documentation about dpx but perhaps I'm not looking in the right place?

I exported out dpx with video data levels, and although the color got closer to what it should be, it's still not close to the reference from the colorist. 

Hi 

I have just experienced similar problems with DPX files provided by an engineer for calibrating client monitors.

His files were video levels, and the luminance levels were raised too high in MC.

MC automatically applied a "linear to Rec709/2020" colour adapter [visible by checking source settings of the linked clip], and I removed this hoping it would fix the problem. It helped, but black levels were still not right.

The engineer suggested that Avid was misreading/misinterpreting the metadata flags in the DPX files.

When you say you output from MC with video data levels, how did you achieve that? I

f you link to the DPX 'as is' without applying any scaling colour transformation, then the 'keep as legal range' export  setting doesn't ensure video levels, it merely avoids  a scale up to full range, so perpetuating the problem caused by misreading the file in the first place.
