Roboform hexadecimal color code generator12/16/2023 The table starts with the original 16 colors (0-15). Where should be replaced with the color index from 0 to 255 of the following color table: The following escape codes tells the terminal to use the given color ID: ESC Code Sequence Terminals that support the aixterm specification provides bright versions of the ISO colors, without the need to use the bold modifier: Color Name # Set style to dimmed white foreground with red background. These have their own set of codes, mirroring the normal colors, but with an additional 1 in their codes: Most terminals, apart from the basic set of 8 colors, also support the "bright" or "bold" colors. Note: the Reset color is the reset code that resets all colors and text effects, Use Default color to reset colors only. These colors are set by the user, but have commonly defined meanings. Most terminals support 8 and 16 colors, as well as 256 (8-bit) colors. The ESC[21m sequence is a non-specified sequence for double underline mode and only work in some terminals and is reset with ESC[24m. Note: Both dim and bold modes are reset with the ESC[22m sequence. Note: Some terminals may not support some of the graphic mode sequences listed above. Set graphics modes for cell, separated by semicolon ( ). You can use \r after erasing the line, to return the cursor to the start of the current line. Note: Erasing the line won't move the cursor, meaning that the cursor will stay at the last position it was at before the line was erased. It is therefore recommended to use DEC sequences. xterm and derived) support both SCO and DEC sequences, they are likely to have different functionality. Note: Some sequences, like saving and restoring cursors, are private sequences and are not standardized. Restores the cursor to the last saved position (SCO) Restores the cursor to the last saved position (DEC) Moves cursor one line up, scrolling if needed Request cursor position (reports as ESC[#R) Moves cursor to beginning of previous line, # lines up Moves cursor to beginning of next line, # lines down This is a common representation (and input method) and historically comes from one of the VT series of terminals. ASCII code 1 would be ^A (Ctrl-A), while ASCII code 7 (BEL) would be ^G (Ctrl-G). Note: The Ctrl-Key representation is simply associating the non-printable characters from ASCII code 1 with the printable (letter) characters from ASCII code 65 ("A"). It is recommended to use the decimal, octal or hex representation as escape code. Var blue = Math.Note: Some control escape sequences, like \e for ESC, are not guaranteed to work in all languages and compilers. Var green = Math.round((rand_2 + baseGreen) / 2) Var red = Math.round((rand_1 + baseRed) / 2) Var seed = input_str.charCodeAt(0) ^ input_str.charCodeAt(1) for seed just take bitwise XOR of first two chars lazy seeded random hack to get values from 0 - 256 TODO: adjust base colour values below based on theme every string with the same first two chars will generate the same pastel colour Inspired by David Crow's answer here: Algorithm to randomly generate an aesthetically-pleasing color palette //magic to convert strings to a nice pastel colour based on first two chars It could be easily extended so that the seed is the XOR of all chars in the string, rather than just the first two. It uses the first two chars of the string as a random seed, then generates R/G/B based on that seed. Here's a solution I came up with to generate aesthetically pleasing pastel colours based on an input string. While this code uses hard-coded colors, you are at least guaranteed to know during development exactly how much contrast you will see between colors in production.Ĭolor list has been lifted from this SO answer, there are other lists with more colors. I suppose you could always add more colors. While this has a limit to only 64 colors, I find most humans can't really tell the difference after that anyway. Will return the same color as the first time Instance.stringToColorHash = instance.veryDifferentColors For every new string, assign the next color in the list: // Takes any string and converts it into a #RRGGBB color. The easiest way I have found to get around that is to pre-populate a list of very different colors. I find that generating random colors tends to create colors that do not have enough contrast for my taste.
