Rainbow is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
- Task
- Print out the word 'RAINBOW' to the screen with every character being a different color of the rainbow.

jq
The following assumes the terminal supports the ANSI RGB codes, and has been tested using iTerm2.
def colors: [
[255, 0, 0], # red
[255, 128, 0], # orange
[255, 255, 0], # yellow
[ 0, 255, 0], # green
[ 0, 0, 255], # blue
[ 75, 0, 130], # indigo
[128, 0, 255] # violet
];
def rainbow($s):
# ;38 is the extended foreground color code
# ;2 indicates RGB digits follow
def e: "\u001B"; # ESCAPE
reduce range(0; $s|length) as $j ("";
($j % 7) as $i
| . + "\(e)[38;2;\(colors[$i][0]);\(colors[$i][1]);\(colors[$i][2])m\($s[$i:$i+1])" )
+ "\(e)[0m";

The Raspberry Pi versions of the language require a graphic mode for colored text (unlike the MS-DOS versions), but they compensate by supporting this unusual string indexing (which only works with the interpreted MS-DOS version).
char I;
[SetVid($13); \set 320x200x8 VGA graphics
for I:= 0 to 6 do
[Attrib(32+I+I); \set color attribute
ChOut(6, I("RAINBOW "));
];
