We have a big application on the site and we have a few links which are, let\'s say blue color like the blue links on this site. Now I want to make some other links, but wit
You could use a little javascript to calculate the darker and lighter color using the rgb().
Fiddle : Not really nice, but it is just for illustration.
What it essentially does is sets a color and selects 20 colors with the same amount (compared to one another) of rgb only with 10 apart.
for (var i=-10; i < $('.row:eq(0) .block').length/2 ; i++) {
var r = 91;
var g = 192;
var b = 222;
$('.row:eq(1) .block:eq('+(i+10)+')').css('background' , color(r+(i*10),g+(i*10),b+ (i*10)) );
};
