Color-Coding Ancestry DNA Matches

Last week I began the Research Like a Pro With DNA study group, hosted by Diana Elder, Nicole Dyer, and Robin Wirthlin of Family Locket. I’ve been excited to learn more about using DNA as an additional source of evidence in my research and I am learning so much already! It’s exciting that we have the ability to use DNA in our research! One of our assignments for the week was to assess our closest DNA matches. As part of this assignment, I began color-coding each of my matches using Ancestry DNA’s color tags.

I thought I had formulated a good plan for my color-coding system but quickly realized I needed to make some adjustments. After thinking and re-thinking, here is what I came up with:

Color-Coding Guide for DNA Matches

First, I assign each match to either my paternal line (medium teal dot) or my maternal line (magenta dot). This allows me to set a filter to show only paternal matches or maternal matches, depending on which side of the family I am working on. Then, I assign another dot based on which ancestral couple is our Most Recent Common Ancestor (MRCA). Those with my paternal grandparents as MRCA’s receive a dark teal dot. I chose teal because it’s a mix of blue and green. Then, ancestral couples on my paternal grandfather’s line receive varying shades of green, and those on my paternal grandmother’s line are assigned varying shades of blue. If I know the match is on my paternal side but I’m not quite sure who the MRCA is, I simply assign the medium teal dot indicating paternal side. Now if I spot a teal, blue or green dot, I know the match belongs to the paternal side of my family.

I used the same idea for ancestral couples on my maternal grandparents’ line. Those matches with my maternal grandparents as MRCA’s receive a violet dot, because violet is a mix of red and purple. Then, ancestral couples on my maternal grandfather’s line receive dots in the red family. Ancestral couples on the maternal grandmother’s line receive purple dots. Matches on the maternal side with an undetermined MRCA receive only a magenta dot.

So far, this system seems to be working for me. In my mind, it made more sense to assign a color to a couple rather than an individual. I am not sure what I will do with MRCA’s beyond the 2nd-great level. I am considering continuing on with the lightest shade of whatever color is assigned to that branch of the family.

If you are interested in creating your own color-coding guide, I created mine after reading instructions in this blog post from The DNA Geek, Leah Larkin. She includes a link to her “dummy tree” on Ancestry where she has shared the color swatch files for you to upload as profile pictures on your guide.

I’d love to hear how you are using Ancestry DNA’s color tags to sort your matches! Let me know in the comments below!
