How to Get Vibrant Colors with Blender

You can render incredible colors directly in Blender, and the secret to it is the mysterious Raw view transform that most people ignore.

A view transform is how Blender can display your render correctly on your screen. A 3D scene can have arbitrarily bright lights, but your monitor or phone screen can only get so bright, so the values of the colors in your render need to be transformed to fit within the constraints of the display. 

AgX is Blender's newest view transform for rendering and it's incredible at preserving details on brightly lit and / or highly saturated surfaces. However, many find AgX (and its predecessor, Filmic) to appear too dull, washed out, or desaturated.

The reason for this is that the result of AgX or Filmic is not necessarily the final step in the production of the image. What you get out of Blender when rendering with AgX is a bit like what you get out of a nice camera when shooting in a detail preserving format.
