Mathematical Formula For Picking Realistic Hair and Eye Colors

[cwurts]

For hair colors:

1)  choose random number x from (1 to 206); Green = x+39
2)  choose random number y from (0 to 100); Blue = (102 - ABS(142-Green)) * y / 100
3)  choose random number z from (0 to 80); Red = (102 - ABS(142-Green)) * 0.4 + z + Green

This gives a good range of black, brown, red and blonde hair colors, without any nonsense.  Red is a bit more prominent than I'd like, but that's okay.  I'm hoping someone will add this function as a randomize button in CAS, but all I can do is hope....

My apologies - I made a huge mistake here with the hair colors.  Here is the real formula:

1)  choose random number x from (0..1); Red = x*255
2)  choose random number y from (0..1); Green = (y*0.2083+0.625)*Red
3)  choose random number z from (0..1); Blue = 0.88*y*z*Green

For eye colors:

1) choose random number x from (0 to 223); Blue = x
2) choose random number y from (1 to 2);
3) choose random number z from (0 to 223/y); Red = z; Green = z*y
4) Flip a coin - if tails, switch the red and green values

This gives blues, golds, and any range between brown and green.

Now if you can make those distributions match the real-world results, you'll be onto something.

This is the same guy whose greatest hits include "Rainy Day Activities!  Come Help Me Sort Over 9000 Pointless Job Titles!" and "Get Me to the Grocery, I Like to Micromanage My Entire Sims 3 Neighborhood At Once".  I'm not really shocked that his latest offering is "Let's Suck All the Fun Out of Create-a-Sim!"

[J. M. Pescado]

I think this was more aimed for use by modders than use by players. It also has no relevance to the actual gameplay itself, so I am moving this out of Facts and Strategery, as it does not represent a usable strategery.

But you do get to flip a coin, jezzer. That's a whole world of fun by itself.

Not a techhead here, but if you write a working formula for corrected genetics, I shall forever lick your labia.

[cwurts]

I have corrected the mathematical formula for realistic hair colors.  The old formula was causing sim's hair to be pink.  DO NOT USE THE OLD FORMULA.  IT WILL RUIN YOUR SIM'S HAIR AND YOU WILL NOT BE ABLE TO FIX IT WITHOUT A CAS MOD!!!

I apologize for any inconvenience I may have caused.

[J. M. Pescado]

I don't think anyone actually DID use that formula, because your formula is completely unsuitable for human usage and only a machine would process that.

A calculator is sufficient.  Am I to understand that the average simmer who frequents this site does not own a calculator?  I have one beside my computer at all times.  Come to think of it, I have one on my computer at all times.

Hookah, you still ain't getting what he trying to say, are ya?
Make a fucking mod out of the text you posted, cuntwart.

[Moryrie]

Mod, or no mod, why would someone want this? Because skintones are not involved, and even if one did manage to implement skintones as well... It would not result in 'accurate looking' results, because even using the formulas, the game would still manage to generate the Obese, Platinum Blond, Yellow Eyed, Black people that I always seem to find in my game if it is left to generate townies on it's own. It seems impossible, but I swear 80% of the black people the game spawns are blond.

Yeah. I'd rather just editsim any sim I don't like the looks of. Less complicated.

But...  but...  this way, you have equations!  Fun with math!  COME ON.

[soozelwoozel]

Right, well Moryrie is definitely not getting an invite to my Calculus Céilidh. Jes, you bring the algebra, I will provide long division and cwunts is on punch duty. A rollicking good time will be had by all.

This.

Plus, if his goal were to get this sort of formula used when the game spawns sims I could maybe understand, though it's misguided for the reasons above regarding the frequency of uncommon skin to hair/eye combinations. However, in the original post he mentions wanting it to be made into a randomize button in the CAS. Uh, is it really that hard to take a second to move the cursor on a color wheel to change a hair color you don't like?

[cwurts]

If the skintone slider is right of center, then use random numbers between 0 and 0.5 instead of 0 and 1, for both the eyes and hair.  Is that good enough?

And randomly generated townies sucks for other reasons as well - they hardly ever use the more detailed sliders, and never the custom ones.  That's why you have to put more effort into tweaking them - enough effort to make using these formulas seem less tedious by comparison.

[Moryrie]

But eye/skin/and hair color are the easiest things to tweak in those cases. And your formula does nothing about facial sculpting, which is what makes any sim look like any particular ethnicity at all. Giving a Korean person blond hair, blue contacts is not going to make them look German, even if they're super pale. If I dyed my hair black, and wore dark brown contacts, I'd still never pass for Japanese, without extreme plastic surgery.

Same goes for sims. If you want to make a sim look like something specific, You are going to have to do all the work yourself, in CAS, because a random button is not going to help, and even with the 'No Vanilla Pudding' feature of Awesomemod, the results are not what one wants, because the generic EA selection of noses/mouths/eyes/headshapes, sucks. Randomizing that sucks more than just picking them out yourself.

And I also rather doubt that your formula would have results in keeping with the statistics of reality. Default everyone to having olive skin, brown eyes, and black/dark brown hair, and you'll be closer to matching that.

Also NoVanillaPudding seems to employ a Walmart algorithm giving a quite high percentage of obese sims.

So yeah, basically randomizing will always suck and giving odd or less than ideal results that require fine tuning or a lot ignoring.

[J. M. Pescado]

Also NoVanillaPudding seems to employ a Walmart algorithm giving a quite high percentage of obese sims.

The bodyshapes of sims have always been entirely random. The reason there is a high percentage of obese sims is because about anything over about 2/3 fatness looks rather obese. Since the range chosen is random, you're going to get a good third of your neighborhood as fatasses. Getting a neighborhood of anorexics is somewhat less likely because the line at which it becomes visible is more like 10%, AND it must be really combined with a lack of beefy arm slider to be apparent, so the actual percentage is closer to like 5% or less. Additionally, a baggy uniform, of which there are many, will hide it even more, while doing nothing to conceal the Landwhale syndrome.
