1213: "Combination Vision Test"

Alt text: "If you see two numbers but they're both the same and you have to squint to read them, you have synesthesia, colorblindness, diplopia, and myopia."

Well, I just see a circle filled with small numbers, so I guess I'm not special.

I'm surprised that I got more history than computers. I guess it's because I don't recognize microprocessors on sight and I don't mess around with 512KB RAM computers?

This is what I love about xkcd.
I didn't know about synthesia before seeing this comic, it motivated me to look it up on Wikipedia.
And now that I have it makes me appreciate the wittiness of the comic all the more :D

I started coloring each number, but... yeah, that's a lot of work. Someone color those numbers so we can see what a synesthesic sees!

I'm guessing people with grapheme->color synethesia see different numbers in different colors, but I'm assuming Randal used wiki's example for his coloring...
0=black
1=cyan
2=blue
3=red
4=dark green
5=dark yellow
6=red
7=navy
8=purple
9=bright red

Huh. I didn't get it, as I thought synesthesia was "seeing" music as colors, so I looked up synesthesia on Wikipedia. Learned something new; I didn't know it was any kind of coupling like that. Interesting.

...It's not intermittent, I always associate with a color. It's just that when I look at that picture, I don't even see numbers, I just see black symbols everywhere. If I focus on one part there are some colors, but the numbers are too jumbled in some places. If they were more spaced out, it might work better....

I'm both a synesthetic and color blind, but I'm an associator, not a projector, so this is mostly just a large blob of letters.

Although I have to tell you, having both conditions does make it hard to remember things sometimes. I can remember getting scientific terms that begin with "R" and "P" mixed up because the purply blue spectrum of colors is muddled for me, meaning that I can't rely on the color of the words to distinguish between the two.

I've sometimes joked that it is an unfortunate combination before, but I've never encountered the combination in a setting when I wasn't the one that brought it up.

82? that was what it seemd to look like after a bit of staring. No synesthesia though, just observing the whitespace.

I see colours, arranged in minuscule clusters of red, green, and blue. My brain interprets these, depending on intensity, as either 'black' or 'white'.

The 7s form the number 2 on the right side of the circle.

Still looking for the other number.

Ohhhh, I finally got the gag (d'oh).

If you can not see EITHER big number, then you DO NOT have Synesthesia.

So, spent a few minutes with the paint bucket tool to make this spoiler, and then the forum doesn't let me post it, claiming it's spam..

But yeah, it's 42, with 2,3,5,7,9 "painting" the numbers, with one errant '2' outside the figures.

As someone with deuteranopia, I've often suspected that what other people call "color" is actually just a manifestation of a particular form of synesthesia.

I don't have synesthesia but I could still immediately see the 2. Weird. I guess the combination of having different numbers than the background area and also being a different density made it obvious enough. The 4 I couldn't see until I knew it was there, I think because the numbers making it up were spaced out at the same density as the background noise.

Well, according to the comic, that means I apparently have both conditions. My doctors would disagree, but what do they know compared to XKCD?

You re sure you looked ub synthesia, not synesthesia? And that helped you to get the joke? :)

I have letter/number -> color synesthesia, and I don't think that's how it works... it's not a visual thing where you hallucinate colors when you see letters/numbers on a piece of paper or a computer screen. It's just an association, like a strong feeling of a color. Kind of like when you see the word "green", you think of green, but you don't see green. Same thing with synesthesia but with individual letters/numbers. (i.e., D, J, P, and V are all the same dark green to me)

That is absurd. "P" and "R" are brown.

I have synesthesia, but things aren't always the same colour to me. Ps are usually yellow, but sometimes orange. E tends to be black or navy blue. The word "red" is green. The word "green" is blue. "Blue" is purple, "purple" is purple with yellow Ps. But I see nothing in the comic except the little numbers, in black and white. It doesn't even trigger my synesthesia. I don't know why.

ETA: Just noticed that lower-case As are pink, while upper-case As are kinda salmon-y orange. And Times New Roman does this to me more than any other font.

ETA II: I usually see the colour as replacing the colour that's there, but sometimes it's a halo around the letter.

I think I see Infinity in there. The left loop is the top half of the 4, and the right loop is the top half of the 2.

Not in the colours, just if you look at it the right way.

Thus, I don't get the caption. I assumed that one of the two numbers would be invisible to a dichromat.

Hmm. So far as I know, the only one of those conditions I have is myopia. If I take off my glasses and squint, I can almost make out the number "44".

I liked the joke. But synesthesia of course doesn't work like that. The exact associations are different for different people, and it seems unlikely that colour blindness would actually matter.

One thing that has always shocked me about synesthesia is how common it is. I remember the subject coming up in a group of friends of mine, and in the end I felt rather left out, as I was pretty much the only one without any form of it.

Also, if you think about it, number-colour synesthesia is kind of like a real life super power, since it does actually allow you to see patterns in numbers a lot faster.

Well, the colours in nerd65536's image (awesome work by the way) are kinda arbitrarily selected, since different people with synesthesia see things as different colours (or not even necessarily colours - it varies). So really the idea that some person sees 3's as red and 4's as green, and thus can't tell the difference in colour between 3's and 4's because they're red/green colourblind... doesn't really make a lot of sense, since what colour is what is subjective to start with.

However, the "4" is made out of 2, 3, 5 and 7, while the "2" is made out of 3, 5, 7, 9. So if you coloured it such that it's specifically the 2s or the 9s that stand out from their surroundings, you might only be able to make out one number or the other. Grab nerd's image and open it up in an image editor that can edit the palette (in GIMP, open the "Colourmap" panel) and tinker, you can probably come up with something.

I have letter (musical letter/music)/colour synesthesia, not number, but you can still see the number (though I thought it could've been 98 or 92 before 42).

Man, I hate these things with a passion (yeah, I know, they're called Ishihara plates) - I could never really get them right, even seeing part of the numbers (they're purposefully constructed so you see a _different_ number, not none) yet I never had the problem of confusing any color with any other, as far as I can tell. Yet somehow, around here, you are still tested with this stupid thing in relation to your driver's license. It feels like living in the bloody dark ages - and incidentally it leads to memorizing what one is supposed to see based on the partials... </rant>
