: Random Color Patterns I'm trying to create hexagonal pattern of slightly offset colors. Similar to Code Review's background, but with hexagons. I've attempted to draw a hexagon and slightly change

A quickly written Javascript to randomize the RGB fill color of a selected set of objects:

var adjustRanges = {
red:{min:-40, max:40},
green:{min:-40, max:40},
blue:{min:-40, max:40}
};

objects = app.selection;
for (i=0; i<objects.length; i++)
{
color = objects[i].fillColor;
if (color instanceof RGBColor)
{
r = color.red+adjustRanges.red.min+Math.random()*(adjustRanges.red.max-adjustRanges.red.min);
if (r < 0) r = 0; if (r > 255) r = 255;

g = color.green+adjustRanges.green.min+Math.random()*(adjustRanges.green.max-adjustRanges.green.min);
if (g < 0) g = 0; if (g > 255) g = 255;

b = color.blue+adjustRanges.blue.min+Math.random()*(adjustRanges.blue.max-adjustRanges.blue.min);
if (b < 0) b = 0; if (b > 255) b = 255;

c = new RGBColor();
c.red = r; c.green = g; c.blue = b;

objects[i].fillColor = c;
}
}


Save as "changeColors.jsx" in your local Illustrator's Scripts folder so it will appear in the File > Scripts menu next time you restart Illustrator, or anywhere else (and you'll have to browse for its location).

You can change the min/max adjustment values at will; for example, setting these values to 0 for both red and blue will only change the Green component.

To get uniform graphics use the snap to grid setting, you can then scale it to your desired size in Illustrator. Check out Chris Spooners blog post about a similar sort of project.
