Indeed. It's called synesthesia, and works for many different things, like months, letters and numbers, songs and names.
Well... /yes/, color-temporal form as this thread describes is technically a form of synesthesia... but I wouldn't say everyone who can rattle off a list like here is a synesthete. It's not 'I'm thinking about it, and I'd say Tuesday is pink because Tuscany gave me the Pink Bow' or 'December looks like red and green! Bows and christmas trees, silly!' It's always just ~there~, and wouldn't take you any more thought than to think, "okay, even though 3 is just a symbol with no syllables to tell me how to pronounce it, I'm going to call it 'three' because that's how I've done it for the whole of my previous life". That would make as much sense as a synesthete saying "let me think... 'd' should evoke blue-purple plaid, right? yeah, that looks right. and then 'r' is the one that feels like a carrot..."
I'm not saying these people don't honestly feel some connection to what they're connecting. I'm just saying, why not try again in a year and see if the answers hold. For the most part, I sincerely doubt it.
(By the way, what stat were you using for 'most people'? Wiki says
1 in 23 which would mean, rounding up to compensate the higher number of girls on this forum and the higher likelihood for girls to have it, roughly 20 people on this forum have the chance of having some form of synesthesia. It might be [general-specific] you, congrats! but then you've got a 95.5% chance of ~not~ having any sort of synesthesia at all. so... don't bet on it :D)
The brain has a tendency to form patterns that aren't there. I mean, this is cute, and when I was [still general] your age, I thought all these sorts of things too - I was a synesthetic empath! I could see auras and predict the future in my dreams! But then I grew up and now I don't. (believe I can. I never really could, of course.)
Also, if you're into this sort of stuff, I highly recommend
A Mango-Shaped Space by Wendy Mass. The story of a synesthetic girl! It's nicely-written.
Anyway, on topic. Monday is a really hot
red, sort of
darkened burned spots on some bits, and thin and brittle like old paper; Tuesday is a cool, smooth but rough, kind of? like sandstone?
yellow,
yellow-brown... what was that word they used for Cassidy's hair... not gold, not blonde... oh well, something like that. Wednesday's
water-blue, cool and trickly with just a hint of fuzziness, like a water stone with mold growing over, or what it feels like to
run your fingers through a buzzcut. Thursday's solid, static, no-nonsense brown. Also sort of natury, mostly unpolished and... flaky? but
definitely dark-brown, ranging from a kind of
light-dark-brown to
almost-black-dark-brown. Friday is sparkly, like mahou shoujo wand sparkles. Like that photoshop filter sparkle. And Friday's got striated
gold and
silver, like an ore. Actually it's almost unnaturally sparkly enough to be akin to glitter glue, except it's a lot heavier, so I call it an ore. Saturday is a
cool black/
gunmetal gray/...
not so much /royal/ purple, much darker than that, but that general hue? And Saturday's kind of melty-gummy. Like silly putty that's been left out long enough but not long enough to break. Sunday is all pastels, mostly
lilac and
light, faded yellow and
pink, the sort of things you'd see to paint a baby's room. Sunday's most aethereal, and doesn't really have a feeling-sense... it feels like popping a bubble, or like steam without the heat or a sea breeze without the scent. It's aethereal, and so very ephemeral (except continuously ephemereal, which is even harder to describe). (note: the colors are terribly terribly incorrect, I'd need at least 100x100 photo examples if not 3D renders, but I cba and so tried to get sort of maybe close with what bbcode gives.)
Saying which I like 'best' is like... 'which of your toes do you like best'. You've always had each of your toes, and you never really think about them until someone brings them up in discussion, but do you have a favorite? You could say "my favorite is the big toe because it's most useful" - and here I might say "who doesn't like friday, getting off from school?!". or maybe "I think the fourth one's toenail is prettiest", and I'd say "I really like saturday's color and feel, as well as wednesday's texture and friday's colors". There's a myriad of characteristics to consider.
And here I don't know if I do have synesthesia - I'd have to know what another sees to compare, which is obviously impossible. I am honestly unsure if I'm making all this up or if there's some kind of framework for it in my head: prossibly a mix of both? I'm guessing probably 80% it's all bs, 15% it's bs to some point, and 5% 'you're scientifically rigorously abnormal! hurray!'
... god, I think the caffiene in those painkillers is getting to me. TL;DR: you probably don't have it, but it's still cool, whatever, rock on.
