Morphology
The phrase 'white light' is transparently compositional: the adjective 'white' modifies 'light' to indicate light that appears white, so a learner who knows both words can derive the meaning. This is a basic, cross-linguistically common descriptive pattern rather than an idiom or metaphor, making it immediately accessible to a B1 learner.
Etymology
The term white light comes from the simple image of many colors mixed together: the word white names the result and light is what carries those colors. So white light means light that contains 'all the colors' you can see.
