Topic awaiting preservation: loop through every color (Page 1 of 1)

OK, so I would like to know how to loop through every color. You know how on some of those really annoying pages they have the background loop through every color, well that's what I want. Not to change the background, but to loop through every color. I'm not sure how I would go about it, can anyone help me?

Every color? That's several million colors on a computer.

Except it isn't several million colors, because HTML can't handle so many colors.
I guess you'll have to find a way to walk trough all different combinations in a way that fits the transistion you desire. Hexadecimal numbers always seem to do the trick.

Every color consists of three different teints(from 0 to F, F being actually nr 14). You can alter anyone of them to change the color you want to generate.

Hope this helps, I've just awoken and stuff .

Oh, yea, sorry...

Well, what he most likely wants is to loop through every *hue*, not every single shade of every hue.

here's how I would do it:

var col=.5 // number between 0 and 1 that specifies how far through the color cycle
var red=0;
var green=0;
var blue=0;

if (col < 1/6)
{
red=255;
green = (col/(1/6)) * 255;
}
else if (col < 2/6)
{
green=255;
red=255-((col-1/6)/(1/6))*255;
}
else if (col < 3/6)
{
green=255;
blue=((col-2/6)/(1/6))*255;
}
else if (col < 4/6)
{
blue=255;
green=255-((col-3/6)/(1/6))*255;
}
else if (col < 5/6)
{
blue=255;
red=((col-4/6)/(1/6))*255;
}
else
{
red=255;
blue=255-((col-5/6)/(1/6))*255;
}
red=Math.round(red);
green=Math.round(green);
blue=Math.round(blue);

hmm, I'll have to look through your code some more slime. But actually it's not on a computer, and it's sorta hard to explain, but every color is assigned a red, green, and blue, and each of those can be between 0 and 31 (in decimal). Maybe Slime's code will do it, I'll have to look at it some more.
