I like this idea. Apart from Dawnbringer's 16-color palette which everyone knows and loves (and which I'm using in my WIP), I'm fond of the Tango Icon Theme color palette, though it's designed for user interfaces, not games. But it's really good. As for my own work, I've only created a single palette so far, not-so-well-named Color Grays. It's made algorithmically from color values of the form #ffeedd, #eeddcc, #ddccbb and so on for all possible combinations. That makes 84 of them; add 16 grays from #000 to #fff and you have exactly 100 colors to play with.Fun!

 Now, I'm not so sure what this pallete would be good for. But you never know.

Remember that colors are perceived differently depending on their neighbors. Also, larger splotches of color appear lighter, because (being larger) they physically emit or reflect more light. And you don't always have to use pure colors; gradients and dithering still count as using the same limited palette. I only know the most basic tricks, but I'm pretty sure a color palette is never as limited as it seems.

That said, your own palette looks very interesting on a second look -- so colorful it seems larger! Will definitely keep it in mind for the future. My collection is growing...

I prefer named palettes as I need a name of some sort inorder to add them as variables I can create palettes like yours on the fly so it would be a waste to store anything more then the seed color. I would like some Ideas on organizing these colors I am collecting. for complete palettes like db32 I store these as they are but I want to build a color library of considerable size just for general use. like making other palettes.

I don't make palettes really, I am a programmer working on procedural design tools. seeing your palette just made me think that it could be created from a script rather than storing all that data. sorry I guess that just the programmer in me. if i do make a script to reproduce your palette I will call it GravityPalette1. anyway seeing the Tango Icon gave me the Idea that I could create a custom UI for each palette. that would make them easier to use.

Are you referring to palettes with named colors? Then take a look at the X11 color names, the largest named palette I'm aware of. Or this even longer list of colors, but which doesn't form a palette per se.

I can create palettes like yours on the fly.

Mine, perhaps, since it was created procedurally. But the Gravity palette? Take a look at the actual color codes, they're more subtle than they seem. There's some degree of repeating values in the HSV space, but even there I don't see a rule.

Otherwise, sure, you can make palettes of assorted colors procedurally. Ever heard of Agave?

Yep, beware procedurally generated palettes! My colour choices (which are not always the best) had a general improvement when I began choosing colors according to how they looked rather than to their numeric values (be it RGB or HSV). I think that the point is what claudeb said, that colors look differently according to their neighbors and their placing in the piece (I think the correct term is clustering). That will hardly be captured by the color's numeric values.

By the way, I have a little 16-colors palette of mine. I've been doodling with that for a while, so I'll post it here.

Also, I do not own Super Mario - he's there just for demonstrative purposes.

Intriguing palette, Buch. Kind of dark and red-blue oriented, but I can definitely see it having uses. I took the liberty to put it in GPL format:

Hope this helps!

Edit: I can't help but notice the similarities to Dawnbringer's 16-color palette. Are they coincidental?

@claudeb: you're welcome! Just, it's a WIP palette, so maybe Buch's Palette 0.1 would be a more appropriate name... That being said, now that you mention that, I notice myself similarities with DB16. They were not intended at all. Maybe I've worked so much with that palette that I couldn't help ending up with something similar... I have an extra green, and a purple tone as well, that DB16 has not. But they're very similar nonetheless.

I've made an .aco file (Photoshop color tables) for the palette if anyone finds it useful: https://drive.google.com/file/d/0B3zul1XNyPSfekpTMzJHeEVOZjQ/edit?usp=sh...

if you have to look at the values to tell the difference then its probably not worth worring about.

procedurally generated palettes can be a useful tool  to narrow down your chooses. I prefer them over a color wheel.

Anyone ever look into designing palettes for folks with colour-blindness?

Really! If you can tell a palette was generated mechanically just by looking at it... then how come you were wrong about Gravity's? Pro tip: see what I wrote above about neighboring colors influencing each other, and the degree of coverage altering your perception of a color. Ever watched a graphic artist at work? Even they make sure to check out the hex code, despite having more than enough practice to eyeball colors. It's that subtle. And yes, the human eye can distinguish shades quite close to each other. Just... not always in the same way.

Edit: for that matter, I couldn't help but notice that mechanically chosen colors, such as those in the 215-color web-safe palette, always look a little strident, a little fake; the artists I worked with would often chastise me for not picking them by sight, such that they'll have a little randomness to them. In turn, I would marvel at the way their own choices would come to life on the screen, looking more vivid and natural than anything I'd have picked up. It really does make that much of a difference.

Anyone ever look into designing palettes for folks with colour-blindness?

Not me; I know there's research in this field, and color blindness simulators online, mostly for web developers, but I haven't looked closely into the issue. (Pun not intended.) It's tricky, because there are several kinds of color blindness, and people have it in various degrees. Mostly I just try to provide high contrast, and not rely on color exclusively.

thats the point. I couldn't so why would I worry about it.

Because you were wrong. That is the entire point. Try to generate the same colors mechanically; see for yourself. I predict you won't even come close to the originals.

colour picking also effects the video hardware, why a lot stick to web-safe colours. They are an ASSumption they'll look the same on all systems.

Simple bright SMS compatible 16 colour palette (nearly EGA compatible, RGB222 levels differ slightly):

Alternate softer version:

Used here.

I'm going to use x11 palette (the one with the names) in the game I'm working on right now, and I made .aco, .gpl and .pal files for it. All colors in the .aco file were properly named.

Here's the png file:

Good work, maruki! And since you resurrected the thread anyway, here's the palette I created for my game RogueBot:

I love the way it turned out so regular, despite being created haphazardly, as I needed new colors to go along with the old ones. And it's pure coincidence that it came out 16 colors in size. So it was a lot of fun. Enjoy!

holy moley, I just stumbled onto the palette mother load!
