cho-rok-ssaek. The ㄱ ending 록 forces the following ㅅ into a tensed ㅆ, so the final block sounds much harder than the spelling suggests.
choroksaek
Three flat beats with a held silence where the ㄱ closure sits. The rule on display is post-obstruent tensing, applying here across a morpheme boundary inside a single word: the 색 is the same one in 빨간색, but its consonant hardens because of what precedes it.

이 우산은 초록색이에요 releases that trapped ㄱ at last -- with 이에요 attached it hops forward and voices, giving cho-rok-ssae-gi-e-yo. One word therefore carries both a tensed ㅆ and a resyllabified g in the same breath.
Reading the spelling literally gives 'cho-rok-saek' with a soft s, which sounds slack to a Korean ear; the ㅅ has to tense after that k. Beginners also flatten both ㅗ vowels into 'uh', when 초 and 록 each need properly rounded lips or the word starts blurring toward shapes built on ㅓ.
