A bot that tweets out random hex colors.
You can browse 255 popular colors according to Twitter faves/retweets. (Currently reflects a snapshot of pre-October 2017 tweets, due to Twitter's API and bot shenanigans.)
Runs on Cheap Bots, Done Quick! and Cheap Boots, Toot Sweet! in Tracery format.

}The PNG image that accompanies each hex color toot/tweet is generated by a script that uses PHP's GD module.
<?php
function generate_image($hex) {
$im = imagecreatetruecolor(527, 262);
list($r, $g, $b) = sscanf($hex, "%02x%02x%02x");
if (($r + $g + $b) > 382) {
$tr = max(0, $r - 50);
$tg = max(0, $g - 50);
$tb = max(0, $b - 50);
} else {
$tr = min(255, $r + 50);
$tg = min(255, $g + 50);
$tb = min(255, $b + 50);
}
$bg_color = imagecolorallocate($im, $r, $g, $b);
$text_color = imagecolorallocate($im, $tr, $tg, $tb);
imagefill ($im, 0, 0, $bg_color);
imagettftext($im, 24, 0, 186, 142, $text_color, __DIR__ . '/vera_sans/Vera.ttf', strtoupper("#$hex"));
imagepng($im);
