In sparkline.php there is a list of colour defaults
I edited that to the colour i wanted,
function SetColorDefaults() {
$this->Debug("Sparkline :: SetColorDefaults()", DEBUG_SET);
$colorDefaults = array(array('aqua', '#00FFFF'),
array('black', '#010101'), // TODO failure if 000000?
array('blue', '#0000FF'),
array('fuscia', '#FF00FF'),
array('gray', '#EEEEEE'),
array('grey', '#808080'),
array('green', '#008000'),
array('lime', '#00FF00'),
array('maroon', '#800000'),
array('navy', '#000080'),
array('olive', '#808000'),
array('purple', '#800080'),
array('red', '#FF0000'),
array('silver', '#C0C0C0'),
array('teal', '#008080'),
array('white', '#FFFFFF'),
array('yellow', '#FFFF00'));
Thee, further up in the sparline.php i edited the colour that i just added i further down
$this->colorList = array();
$this->colorBackground = 'gray';
$this->lineSize = 1;
$this->graphAreaPx = array(array(0, 0), array(0, 0)); // px(L, B), px(R, T)
} // function Sparkline
that makes them all change at the same time without having to edit every 1 of the 4 .php files
As you can see, theres 2 greys by default, 1 is grey and the other is gray, i just used the gray
and added the colour i wanted to gray lol
