The Irish Bell Beaker people were genetically like modern north Europeans, and not only did LN-EBA Irish look like that autosomally, they also had R1b and sported significant IBD signals of genealogical relatedness to Yamnaya and even Afanasevo specimens from Siberia. Which shows that not only were the Irish white already 5,000 years ago, they were also part of the vast Indo-European dominion of the Bronze Age resulting from having expanded in all directions from the homeland in ~Ukraine. The people inhabiting Ireland before the beakers were largely similar to modern South Europeans.
