Opera error: uncaught exception: TypeError: cannot convert 'xxxxxx' to object

I came today to show an error caused by an operation in jQuery about converting an object, here is the code (function setColor (x, y)):

colourpixel = $('#colour').css('background-color').match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);//["rgb(0, 70, 255", "0", "70", "255"]

var canvas = document.createElement('canvas');
canvas.height=190;
canvas.width=190;
canvascontext = canvas.getContext("2d");
defaultdata = $('#light').get(0).getContext("2d").getImageData(0,0,190,190);
canvascontext.putImageData(defaultdata,0,0);

canvascontext.globalCompositeOperation = 'destination-atop';
canvascontext.fillStyle='rgb( '+colourpixel[1]+', '+colourpixel[2]+', '+colourpixel[3]+')';

And here is the error caused by opera:

Uncaught exception: TypeError: Cannot convert 'colourpixel' to object  
Error thrown at line 157, column 1 in setColor(x, y) in   file://localhost/home/angelus/Desarrollo/webs/ColorP/functions.js:

    return typeof c!=="undefined"&&!c.event.triggered?c.event.handle.apply(o.elem,arguments):w

I tried to create an object as an array (var colourpixel = new Array ();), but nothing starts.

Thank you in advance!

I'm not sure if this is the best fix since I am not dealing with this color situation at all, but here the problem is this:

In opera, when you set a style such rgb(...)as:

<div id="colour" style="background-color: rgb(0, 70, 255);">โ€‹

$('#colour').css('background-color') : "rgb(0, 70, 255)", Opera, "#0046ff", , colourpixel be null, . , , null[1].

, , , Opera.
