Re: [Avid-L2] Reminder of how my brain will fool my eyes or is it vice versa.

Yep! When I teach about this I reveal that your eyes (brain, really, I guess) are essentially lying to you all the time. There are a few classic examples of how the brain interprets/misinterprets luma and chroma information based on various assumptions the brain makes automatically. 

Here's another one:

As the note in the top left corner states, squares A and B are the same value of gray. If you're dubious, bring the image into Photoshop and use the Color Picker (Eyedropper) and look at the RGB values.

For some info on color and our lying eyes, Google for SIMULTANEOUS CONTRAST; and SUCCESSIVE CONTRAST.

Cheers!
