How to create ROIs with MNI coordinate and draw on brain

Dear Professor,

I have some ROIs coordinates in MNI format, including both cortical and sub-cortical points. And I want to visually map it on the brain with different colors. I am using HCP dataset and the its workbench. I am wondering how to create the standard file which contains my ROIs and can be directly drawn on the brain with different colors?

I would truly apprieciate if you could provide me with some hints.

Thank you.
