You can make and share palettes here. Don't rate palettes, just create a palette and describe uses for colors. Note that 3 and 9 color palettes can be used for ternary computer storage. My palettes are text-based so you can modify source code. It's in this format:
[color=black]█[/color]
black, blue, red, magenta, gray, lime, cyan, yellow, white, #ff7f00, etc...
My 2 color palette:
██This is a basic 2-color palette, intended for basic text (think yellow on black). Could change the yellow color into cyan, green or white.
My 3 color palette:
███The cyan makes a sky, the yellow is for sun. Dithering them results in green for grass. You could also dither yellow with black for dirt, or cyan with black for rain.
My 4 color palette:
████This one adds red that could be used for fire and dithered with yellow. Also contains a ramp black-red-yellow that can be used for anti-aliasing.
Classic 8 color palette:
████████Can use any color by dithering. The palette colors are nice and saturated.
My 9 color palette:
█████████Adds gray for anti-aliasing.
I have an image with binary storage palettes (I used my custom font):
16-color palette's utility is to complete biggest gaps (for human eyes) in hue circle, and to add some grays and brown. Colors can be inversed.
256-color palette is a websafe palette with anti-aliasing ramps to create in total 16 equal spaced shades of black-white, black-yellow, black-cyan and black-red.
4096-color palette uses 16 levels/4 bits for red, green and blue.
Grayscale and yellowscale are for anti-aliasing.
