    Hi,

     

    If RGB = r + (g * 256) + (b * 65536), then for

    colorElement == 9118312 (untested code snippet):

     

    var b = Math.floor(colorElement / 65536); // == 139

    var g = Math.floor((colorElement - b * 65536) / 256); // == 34

    var r = colorElement - b * 65536 - g * 256; // == 104

    // 104 + (34 * 256) + (139 * 65536) == 9118312

    // RGB(104, 34, 139) == colorElement

1) I don't 'see a particular example for retrieving the color, but my first thought would be to try $get in the example that says $set

2) Just a hint for the future, URLs are great to include in a post but don't put ( ) around them or that becomes part of the link and we can't click it.  🙂

 

sonya_m  I couldn't find a "retrieve color" example in here even though the header of the article mentions it.  Could you point it out or get us one?  Thanks.
