Just to preface with this: my math is crazy rusty. The notation is right, but the interpretation of it may be wrong. If that's the case, lemme know, and I'll fix it

With that out of the way, on to the meat of this post. A few days ago, I was sitting in the chat when a few people started talking about the possible skins that one can make in Minecraft. And this got my curiosity peeked, so I looked into it.

Lets face the facts first off:

• A standard minecraft skin has 1,568 pixels in it, including the "helmet", 1,184 without the "helmet
  
• A computer can process 16,777,216 different colors and hues
  
• The human eye can detect about 10,000,000 different colors and hues
  

And now the math side of it. Again, I suck at math, so I Googled most of this, and I'm copying from here. Warning! Math lesson ahead!
The formula is: (n + r -1) / r! (n-1)!
This means that n = the number to chose from, and r is the times to take from the pool (n)
The ! is called a factorial function. This just means that 5!=5x4x3x2x1=120
This formula also allows for repetition, where the order doesn't matter (meaning you can use the same color on multiple pixels) .
So what were looking at are four different numbers problems now.

(16777219+1568-1)/1568!(16777216-1)!
(16777219+1184-1)/1184!(16777216-1)!
(10000000+1568-1)/1568!(10000000-1)!
(10000000+1184-1)/1184!(10000000-1)!
Ok, math lesson over.

With those four formulas, we get for numbers. Due to the CRAZY largeness of them, they will have to be in scientific notation. I won't explain them, but *coughcough*link*cough*
So here are the numbers!
ALL possible skins!

• With helmet: 2.31303 Ã� 10^113920099 = 231303 with 113920098 zeros behind it
  
• Without helmet: 1.28912 Ã� 10^113921304 = 128912 with 113921303 zeros behind it
  

Only the skins with the colors humans can see/detect

• With helmet: 5.680668 Ã� 10^65652720 = 5680668 with 65652719 zeros behind it
  
• Without helmet: 3.166007 Ã� 10^65653925 = 3166007 with 65653924 zeros behind it
  

So why did I post this? Mainly because I spent WAY too much time doing the math. But also to raise a point. As it sits, there are currently 680,939 skins on PMC. Assuming those are ALL unique skins, that means there is 17,458,155 skins that you can not submit to PMC because they are either already made or are a single color. and against the rules. You can also throw on another 1,000,000,000 or so just to make sure you cover all the single pixel changes to those 17,458,155 skins (I'm not doing the math for an exact number).
Point being: at this EXACT point in time, there aren't enough skins to even make a measurable dent in any of the above numbers. So no one has any reason to not make a new, unique skin!!
