Hey, I'm red green color blind and much of this is difficult to read, but could be otherwise nice. Try outlining instead of solid fill. And having 2 different color sets can help with different color blindness types red/green and blue/yellow.

  Red/green myself, and personally a selection of one red and one green can work if both are bright enough. This one suffers from using a shades of both, and only both (AFAICT). IOW, again for me personally, one can use one from the red box and one from the green box and that's it. Having various shades of the two most commonly mistaken colors just ain't gonna work for a lot of people. For five items, I'd use something like red/blue/green/white/orange or even beige. But enough bitchin', I appreciate the amount of work and the presentation (color palette not withstanding). Really good work, and I can figure it out despite difficulties with the colors. Off to pinboard.in to file this one away.

    You can also try the website version of this. https://github.com/ericdrowell/BigOCheatSheet https://github.com/ericdrowell/BigOCheatSheet It's even open source, pick colors (or not) at will.

I'd argue that having a poster and memorizing it is actually counter productive. It's easier to know the data structure and think about how they work in the different situations.

Knowing all these sorting algorithms can only be useful for someone just learning what an algorithm or what a complexity means. On day to day basis, they are not used. So if this poster was supposed to be practical, it's not, and if it supposed to be stylized techno-babble kind of poster, it's really uninspired and could use serious style improvements, better background, etc.

Quite hard to distinguish between the two greens. I didn't see that there were two until I found the legend.

  All in all a poorly designed poster of something you needn't have memorized unless you're studying the algorithms specifically for an exam or something.
