If you hit your head on the roof while going through a yellow light, it probably means you were speeding through the intersection to avoid running a red.
The reason the filter appears yellow and is called a "yellow filter" is that only yellow light survives the trip through the filter and lives to emerge from the other side. If you don't hit it with yellow light, nothing comes out. If the light hitting the filter is pure blue and nothing else, you'll see no light come out, i.e. black.
When an object appears yellow, that means that most of the light bouncing off it is yellow light. If there is light of other colors hitting it, it's absorbing everything else except the yellow.

When a yellow book is viewed through a green filter, the filter will absorb most of the yellow light but allow green light to pass through. As a result, the book may appear darker and its yellow color may become less vibrant when viewed through the green filter.
