The Russian pair, a combination of youth and experience, dominated the duet technical routine at Glasgow's Scotstoun Sports Campus, performing to the soundtrack of musical 'Chicago'.
Their compatriots Aleksandr Maltsev and Mayya Gurbanberdieva then underlined their country's familiar dominance in synchro events by taking the duet technical mixed title.
Subbotina, a 17-year-old, and Kolesnichenko, a 24-year-old who has won 13 world titles and was part of Russia's gold medal winning team at the 2016 Rio de Janeiro Olympic Games, are only in the first year of their partnership.
The penultimate duo to perform, they dominated the event with a total of 95.1035 points, in a different league to Ukraine's silver medallists Anastasiya Savchuk and Yelyzaveta Yakhno (92.6188) and Italy's bronze winners Linda Cerruti and Costanza Ferro (89.7519).
