What problem does Highlight DNA Matches by cM solve?
On the AncestryDNA match list, every match looks the same until you read the cM value, and the side assignment (Maternal, Paternal, Both) is buried in small grey text. Finding your strongest matches or scanning for a specific side takes more effort than it should. Highlight DNA Matches by cM paints the cM value in red when it crosses your threshold and tints each match card by which side it belongs to, so you can see your best leads at a glance.
How does Highlight DNA Matches by cM work?
On your AncestryDNA match list, the shared cM value is shown in bold red for any match at or above your cM threshold. Each match card is also colour coded by the side Ancestry has assigned: maternal matches get a pink background, paternal matches get a blue background, matches assigned to both sides get a purple background, and any match whose tree is listed as an unlinked tree is shown in green so you know it needs a connected tree before ThruLines will work for it. All four colours work on shared matches pages, ProTools pages, and every localized version of Ancestry. A small open-in-new-tab icon appears next to each cM value, and clicking the cM value opens DNA Painter’s Shared cM Tool in a new tab with that value pre‑filled.
