How can I create a random pixelated pattern?


I was wondering how I'd go about just taking a couple of specific colors, then having something make a random pixelated picture with those colors.

I was wanting to take the colors from my current avatar and use those colors to make a banner. I tried taking my avatar, making it a PS Pattern, but when I applied the pattern, it looked too repetitive. I want the colors to be randomly placed.

As people have commented, coding would yield the best solution. You can get a good approximation using Image > Adjustments > Gradient Map...

Fill a canvas with 400% noise:

Filter using Pixelate > Mosaic...

Increase the saturation:

And re-tone the image with Gradient Map:
