AI Thread Summary
Synesthesia is a fascinating neurological phenomenon where individuals perceive letters, numbers, and symbols as having distinct colors or sensory attributes. Many artists and creative individuals, including notable figures like Richard Feynman, report experiencing this condition, which can enhance their creative processes. Personal accounts highlight that synesthesia is not necessarily a disability; rather, it can provide unique insights and advantages in perception and memory. The discussion includes references to literature, such as "The Man Who Tasted Shapes" by Richard Cytowic, which explores various forms of synesthesia and their implications. Overall, synesthesia offers a compelling glimpse into the complexities of human perception and cognition.

I wanted to make an observation, small that it may be, Kiichi, you are the third or fourth person since this thread started back in April of this year to add input to it, for which we all are grateful, the last few folks sent me private message and gave me permission to post their experiences with synesthesia.

I hope this trend continues, and second that you stay and become a regular here, there is interesting stuff always going on, and the best Mentors/homework helpers and staff are here as well. A great resource for a growing family too. Enough said.

Holy ... !

I was looking at a web page in deep blue, almost purple background here, with white lettering:

Guess what I saw: partial grapheme -> color synesthesia for letters:

lower case: n,d,h,p,u,f,t,g,n light green
lower case: l,i,o,e,1,8 light pink

Holy crap ! If I rapidly open, close and strobe my eyes, more than 3 times a second, the effect goes away and the letters are pure white !

Woo hoo... now I know what partial grapheme -> color associative synesthesia feels and looks like.
I swear to God, I am shaking as I type this. I can't freaking believe it. By sheer chance, in a search for a missing scientist of all things, thanks, Dr Li, I hope you are alright and they find you intact somewhere.

Rhody... :biggrin:

P.S. RasalHague, do some 3 to 5 second stobing with your eyes, both, left only, right only, and let me know what you see, just for comparison.
Now that I know my form of synesthesia only manifests with dark/blue/purple background, try my page as well with white lettering and let me know what you see.

Another Holy Crap moment, today while reading this thread, "why context sensitive advertising works", I discovered I have a second color grapheme combination that does not display its true colors, Inside the light and darker yellow/green text in the two boxes, the circle in every letter, b,d,g,o,0, P, 9, appears as off white, brighter in the darker inner box than the outer one. The size of the circle inside the letter or number seems to be the trigger. The letters, e, a, and C don't show off white because they are too small or not closed and are not circles. I thought I only had one frequency band of partial color grapheme synesthesia. I was wrong. I have at least two, very weird. I showed the other thread screen to another person in the office, he assured me that all the letters i mentioned are yellow/green. I find this odd and a bit surprising. I guess I shouldn't be by now. Those two backgrounds and choice of fonts are new to me. I guess because the background colors are not pleasing to the eye that they are not used that often.

The though occurs to me, will ovals or slightly misshapened circles do the same thing, even including large letters, or is their some limit to this ? I will have to try to reproduce the RBG color scheme in a document and play with larger and different font sets.

Wait. So how did you know that I perceive numbers as associated with different levels of light? :)

Wait, you both see the little off white circles like I do ? Anyone else in the same boat, chime in here.

Rhody... amazed...

Rhody:

Go to the page in question.
Hit PrtScr.
Open Paint.
Press Ctrl and V to paste the picture in paint.
Zoom in on the white spots and notice the difference.
