Can someone link me to the pattern test where there is a pattern that makes a grey and black color look different? There´s tower shape that makes a shadow that tricks your brain.

I think your question is less than clear. A little further clarification of what pattern you are referring to and why you don't like it may lead to appropriate responses, rather than WTFIHTA?

There are many gray scale and pluge patterns.

... rather than WTFIHTA?WTFITA? :)

I'm pretty sure this is what he is looking for:

Darin. Its not WTFITA its WTFIHTA. Translated cleanly its What exactly is he talking about?

Ahh so. That's it. I was thinking gray scale from 0 IRE to 100 IRE. Now it makes perfect sense.

Darin. Its not WTFITA its WTFIHTA. Translated cleanly its What exactly is he talking about?I know. Mine ended with, "is that acronym". Just kidding around.

Sorry. I guess I am not used to you being a kidder.

BTW. Would better ANSI help or hinder the illusion? Just kidding, ANSI is irrelevant because the shades are the same.
