Krom = Chrome (which is a shiny metal, i like shiny) = Shining
Unos = One (in spanish) + S = Ones
OR
Krom from the greek word "khrôma" meaning Color
Unos from the latin word "ūnus" meaning One

and so Kromunos means Shining/Colorful Ones +｡ﾟφ(ゝω・｀○)+｡ﾟ
i totally knew about the greek/latin words when i made up the name and NOT just accidentally found out about them during a boring quarantine day and also my friends just call me "krom"
