Explaining this concept is quite difficult, which is why I haven't been able to find an answer on Google.
I am currently using Bootstrap 3 and I am trying to create a layout with a full width background image, along with two transparent color backgrounds layered on top. To better illustrate, I have created an example image:

1+2: Combined transparent color background
3+4: Combined transparent color background
1+2+3+4: Combined background image (bottom layer)
If anyone has any insight on whether this is achievable and how to implement it, I would greatly appreciate your help!
