As Jeongmin added a commen,t the colour means "색"(or 색깔) but also you're right. Because we can translate from white to 하얀색 :) You had a spell mistake. GREEN : 초록색 And even if you say 밤색 people get understand you! Don't worry. I hope my comments would help you. :)

Thank you ^-^

If you want to say "하얀색", that means "White Color". It's not just "White". Beside that... we often use "갈색" to say brown color instead of "밤색"
