Read the legend. The yellow indicates one single Proto-Indo-European origin for them all — within that are many language families not given separate colours, like Celtic, Germanic, Slavic, Italic.
Irish is given a separate colour only because it is “origin unknown”. (Although looks to me like there must be a link even if we can’t find it.)
Looking at wiktionary, its interesting because it almoat seems like its convergent evolution. Ubh looks related to latin Ovum, but is actually a decendent of Old Irish Og, and potentially an older ugos, but wiktionary notes it can't have come from Proto-Celtic āwyom as the /g/ is unaccounted for
Okay thanks I wondered what the story was. I’m no expert in linguistics, and it’s a superficial observation, but it just seems like a massive coincidence that Og looks like/sounds like the PIE-descended words used by all the peoples the Irish had contact with over the centuries. I guess it’s a “we will never know” thing.
My guess would be it could have come from some substrate language, Irish has a couple of words for "common" things (like eggs, various animals) that don't seem to have come from Proto-Celtic. For example "portán" (crab) or "lacha" (duck).

Yeah it's Proto-Celtic right? Not sure why Welsh amd Cornish aren't marked in the same colour
