I stumbled on a trick that while working on one project that will help me with another, but I am not sure why it works.
When I set the color of an emission shader to a saturation of 1 the shader appears that color no matter how strong the brightness is set to. However, if it is set to about .85 or lower, the shader becomes white when very bright much like a light would be in a photo. When you apply a glare filter to the output the glare is the color of the emission node while the object itself is still white.
I understand why this would happen in camera, clipping and all of that. What I don't understand is why this happens for lower saturations in Blender and not higher ones.
