So I installed my HSS/Freeplay kit finally, turned dip 8 on, powered up, saved a HS, powered down, turned off dip 8. Now the game saves high scores, the machine IS on freeplay, but the colors are screwed. I have no oranges or tans. Dude's face is gone, can barely see the buns, etc. I DO NOT believe that this is a monitor issue, as everything was looking good before the install. I did scrape some of the tiny traces on the parts side of the board right in front of where I installed the socket and chip on the larger board when I was prying the old socket out with a tiny flat screwdriver. Do you think that could be causing this issue?
 
Did you try re-seating any board connectors?

Yep, tried that. I went into test mode and it gave me 2 rom errors. 9B and 11 or 13B I believe. It's weird. Dude's face is gone, text in the beginning that comes up over the game board is really faint, like you can see the negative image of the text, but there is no color in the text.

9B and 13B are the modified code ROMs for score save and freeplay. They will not pass the extended checksum tests in test mode... so that is normal and nothing to worry about. And they have nothing to do with the graphics.
I would double check the small video connector. I have seen some BT harnesses where it is really easy to mis-align that connector (there's too much side-to-side slop), so be very careful to line that up and center it as best you can.
If you think you might have broken a board trace, you don't need to have a continuity test on your meter to check it. All that does is give you an audible indication that it's measuring ~zero Ohms. Set your meter to its lowest scale and just visually check the value instead.

Where do my leads go, either side of the 'break'?

Yes. Follow the trace in both directions until you find a via (where the trace goes from one side of the board to the other), chip leg, or other component solder point, and put your leads on those points. A good trace will show zero Ohms (or very close to that) on your meter.
 
Here's what it looks like:

It's certainly something in the ROM department. Did you remove or re-seat any other chips? Once I re-seated all of my chips and was getting a similar error. Turns out I accidentally let a tiny chip leg bend outwards and was sticking out of the socket. But im not an expert, so it's just a guess.
