It is patterned for some people: Freckles, moles, vitiligo, etc.

There are patterns we can't even perceive too.

For the purpose of answering the question though, I'd want chromataphors I can change at will!

Human skin actually does have a pattern, we're striped. But usually it's skin coloured stipes on a skin coloured background so it's hard to see.

I'd be down for any pattern if it came with bioluminescence.

Left half of my face black, right half of my face white. Then I could fight those no good people who have a black right side of their face and white left side.

Which one are you?

Why settle for one? In that case, squid skin and change color as you see fit.

Sounds like another thing to be racist about for typical dumb fuck populations.

If human skin was sometimes completely patterned

If?

Gingers would like to have a word with you.

Can I have M05 camo?

I'd like the color and texture shifting of octopodes. That would be pretty fucking cool.

After that, maybe stripes. Spots are something some humans have and it's a mixed bag.

Paisley. Blue.

Jadzia Dax had a nice spotty stripes combo going on. Think I'd start there.

Trill spots!

Well, I have freckles all over the place, so my pattern was chosen already.

A leopard pattern would be cool.

This doesn't answer your question, but I just had a great idea for an art project which includes detailed applications of different protection levels of sunblock, and a tanning bed.

I guess stripes would be an easy place to start. Who wants to try it?

Humans actually have stripes but they're usually invisible unless you are a human chimera or have some other fetal development issues. They trace the path that embryonic stem cells took to make your skin in the womb.

Anyway, I'd just make those visible.

Fractals.

Black and white stripes to match my football ⚽ team.

Argyle

One of those noodle labyrinths from kids menus. Entrance is my mouth, exit is... well you can figure that out.

A pattern that camouflages me from the threats of corporate greed and Capitalism as a whole.

You can completely pattern your skin thanks to tattoo technology already. I'd go for the pattern I have now anyhow: A cheesy white t-shirt pattern on my torso and a brown face and and arms.

Louis Vuitton

I already develop a defined pattern during summer when my outer arms, legs, and back tan significantly faster and darker then my inner and chest regardless of how much sun I get. I think I'd like the same style but with a defined color difference, like Nigerian on the outside and Polish on the inside. Though if I got to pick Unnatural colors I'd go for charcoal grey outside and porcelain inside. Really accent my natural affinity for tattoos.

Invisible. Since I'm that already for society.

I'd be down to be white and brown like a cow or horse, except that I know what vitiligo looks like with human skin and it doesn't really look good so I'd prefer just a solid color (don't care which color though).
