Applying background color to rows in sub grid in supported/unsupported ways

Hi team,

We  have to apply the background color to rows in sub grid but not able to find out any resources for version 8.2/9.0.

we are able to apply colors to Views but when we have taken the same view in sub grid it's not giving coloring so can any one of you suggest what could the best approach for this issue.

Thanks,

Nagaraju Matta.
