What were the 2 common types of light

And is incandescents and the fluorescents, the fame is that the incandescents are light with the more natural effect that is hot, and was called yellow in comparison to the fluorescents that are called white is that white that looks like white little blue, and now have the led, the fluorescents were considered artificial, is a white to bother and the filament lamp is kind of yellow light resemblance to the sunlight the sun is yellow but give the right colour for what is illuminating don't make the thing yellow, but I don't consider the studio yellow light look like to the incandescent lamp light, yellow isn't a light with a filter to be yellow.
