Number is "42". The 4 is composed of 2's and 3's and 7's. The 2 is composed of 3's and 7's and 9's. --RainbowDash (talk) 05:16, 17 May 2013 (UTC)

What about 7s? --81.23.24.34 06:13, 17 May 2013 (UTC)

Also both have 5's. I'm not very good at this counting thing. That link below is way better, anyhow. --RainbowDash (talk) 05:28, 17 May 2013 (UTC)

I'm not confident enough about this to write up an explanation, but given that synesthesia is a sensory experience where the senses blend into each other (hearing colors, tasting sounds, etc...) that a round shape or black and white (why is it not in color? that would help the joke imho) give the sense of a number to the synesthete. The alt text at least makes sense, seeing two big numbers fits with diplopia (double vision) and the squinting covers myopia (nearsightedness) so it is consistent with the main joke, but I feel like I'm really missing something in the main joke.

In the original b&w image, I keep seeing an 8 on the right and a vague 0, 9, or 4 on the left. I'm not certain if the b&w actually has a definite "answer" or specific number(s) one is supposed to be seeing. I seem to recall an xkcd with an Ishihara test before (but can't find it so it may just be a confabulation), in which case this one may be a reference to that and actually have a referential "answer".

I'm not an optometrist, but Chexwarrior,'s explanation of the alt text seems correct to me. 07:00, 17 May 2013 (UTC)
