I was fortunate to work at Texas Instruments during a battle between Epson LCD projector technology and the TI DLP chip technology, centering mostly on the education market.

The speed of the DLP chip was increased to over 110,000 “flips” per second, well beyond what the eye can perceive. Yet anecdotal evidence suggested that a very few people were bothered by the mirror flips (~digital light) verses LCD cubes (~analog light).

That the eye and brain can “see” something so far beyond what the “design” of the eye should allow is fascinating and still under study.

The second article discusses a woman who has a fourth cone (a tetrachromat) which enables even more color perception. I have seen that about 2% of women have some Tetrachromatic vision.

It seems that women in general, see about 8 times the shades of red that any man can. Why else 100’s of red nail polishes for ladies to choose from?

The eye and brain combo is one of the most fascinating areas of research to me.

Thank you for the excellent information.

It’s hard to explain, but I feel color without touching an object. Just as you hear different tones and pitches to recognize someone’s voice, my consciousness feels the vibration associated with various colors. It gets confusing though as the material or surface of the object that has the color also resonates a frequency.

Years ago I was with two geologists who were comparing specimens they collected. I went to pick one of the rocks up and jumped back, saying ouch, that one is hot before I ever touched it. They looked at me like I was crazy.

I went on to “feel” each one without touching the rocks, noting each one had a different feel.

They put all the specimens in a large flat box and put a towel over it, asking me to tell them where each rock was in the box. It was easy.

A couple of months later one of the geologists invited me to go along with him to a geologist’s meeting. It but several hours away, but he insisted, so I went.

Upon arriving, I found that I was their meeting speaker for the evening. They had 30 to 40 styrofoam cups upside down on the lab table with sequential numbers on each and various specimens held inside by tissue paper. They asked me to describe the feel of each sample.

I had never done this previously and it was a total set up.

I went through each sample describing what I felt as the attendees took notes by cup number. Then I sorted them by groups that felt similar.

Allow me to add that to me, they were just rocks as I have zero geologist knowledge.

There was one cup that I set way off to the side from all the other groups as it didn’t even feel like a rock in the cup. (It was an old Indian paint pot used to grind and mix paints)

The group president then flipped over each cup describing what specimen was in each one while the group compared it to their notes of my comments.

I was astonished at the accuracy of the groupings. I feel frequencies resonating from most objects and people.
