What’s the question?
if perspective area what is role of newcode?
i.e overall status–>all projects show
duplications -->duplicate code show
new code—> what will happen
A yellow background is used in SonarQube to indicate that you’re looking at “On New Code” values. (Background on why that’s important here.) Your screenshot shows the Projects page, which is designed to allow you to search/explore your project set. When you switch to the New Code perspective, you’re shown each project’s “On New Code” values (which is why the yellow background is used) and given the opportunity to search/filter by new code values in the left column.
