Imagine Brains

I needed an image of brains to show the status of the learning memorisation. I found one image which was almost exactly what I was looking for. Shiny brain image which would show words like brighting stars. I share the image here for reference from sciencefacts.com.

Here is what I did to create a similar base image. First blueish gradient bacground for the picture.

Then I added sideview of face [side face from nippo-ent.com].

I removed the ear and inverted the image.

Hue changes.

The background gradient needs some other blue.

And then brains.

Inverted and decreased alpha value.

Finalize with some color and brightness settings.

By the way when I was looking for the image photos I noticed that almost every of them were shiny blue. Does blue brain images make them look more scientific or what is the purpose of use of blue?
