How can I change the color of all drawn elements under a single level?

So I have couple of elements under Level-A, they are all in blue, now instead of clicking them one by one, I want to change them all to red. I went to level manager and changed the Level-A color to red, however the drawn elements still remain blue. The only way I can change them to red is by clicking on each of them one by one, and going on element information and changing color to red. Please advise!
