Hey: If you come up with any custom formats you think should be added officially, or have any other issues with bugs or imposed limitations, feel free to contact me (Nelg).

Colors

This tool supports the following style of CSS color codes: hex codes (#f00), named colors (red), RGB (rgb(255,0,0), and HSL (hsl(0,100%,50%)).

It also supports the following features (case sensitive!):

• rainbow - inserts colors of rainbow between red and blue
• rainbowfull - same as before, but adds magenta which is good for stacking rainbows or shifting back to red.
• repeat(#, colors...) - repeat any number of color codes. Example: repeat(4, red, blue)
• orgb(r, g, b) - RGB offset from the previous color.
• ohsl(h, s%, l%) - HSL offset from the previous color. Good for making rainbows. Note that this tool works in RGB internally, so may be prone to error here. Example: red,ohsl(50,0%,0%)
• rainbow2 - shortcut for repeat(5,ohsl(60,0%,0%)) (aka another technically incorrect rainbow)
• $LEN - Number of characters contained in the input text. Example: repeat($LEN,red,green)

Custom Output

In addition to the predefined outputs, you can output the color codes using these variables (not case sensitive!):

• $R, $G, $B - outputs integer color from 0 to 255
• $dR, $dG, $dB - outputs decimal color from 0.0 to 1.0
• $iR, $iG, $iB - outputs integer color from 0 to 15
• $xR, $xG, $xB - outputs hexadecimal color from 0 to f
• $H, $S, $L - outputs hue, saturation, brightness of color from 0.0 to 1.0
• $dH, $dS, $dL - outputs hue from 0-360, brightness from 0-100, value from 0-100
• $hex - hex code of rrggbb from 000000 to ffffff

These can all be mixed and matched as necessary, with the following text output:

• $txt - standard text output
• $xtxt - text output with (limited) protection for HTML

Note that right now, this tool natively works in Armagetron color codes. It will only attempt to work around its limitations (seperating 0 and x, disallowing dark/highlighted colors), and does not attempt to workaround the limitations of any other formats unless otherwise mentioned by the text format above.

• Design:
» Layout is loosely based on an old design by Durf.
» Icons on the tools page were originally by Royce, new icons added will try to follow some of the design language.

is a site that has tools, maps, and more.

This is an LLM-free zone. In general, I am unwilling to use (fight with) any form of "GenAI" to write code or generate images for me. So, for the forseeable future, everything on this site will continue to be written by a very silly goose (wait that's me honk honk) with some parts written by other humans as well (silly hu-mon) rather than any plausible-series-of-words token-eating machine. Even my libraries are out of date, and suddenly that's a good thing!

(This site was at a different domain for probably 11 years until 2026. There, it had been added to and tweaked throughout the years. However, the core of the site hasn't changed much since 2015. But it Ain't Broke!)

This site is also occasionally tested with older browsers, but compatibility is not guarenteed. Although, if you have an old obscure browser and something isn't working that previously did, I guess you can tell me (nelg) about it...
