Thanks for the quick response on this, that fixed my problem. Also, just wondering is there a way to add a title to the default legendWidget? Or would I need to extend it and write custom code in order to do that?

Hi Erik,

The legend predates when we were attempting to normalize how colors are represented.  It looks like it expects a valid CSS representation of color.  You can use the method geo.util.convertColorToHex<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_OpenGeoscience_geojs_blob_master_src_util_init.js-23L305&d=CwMFaQ&c=DsZY2bea7iNIzyp-7sZ0t0F2UfNQZUfZhEPCv_2wBI0&r=sdAMZxqAoPTtVpp0WTsUGE05dS9lBt3NjsK7CxSH_Bc&m=Hy-tQTuLetyz8nCqNejq9Io68RW4huSJDI2WADFlvbM&s=H_DU9f2z_BZkqjS47SJk7eRIDrX7lx_5EBLjX3LckI8&e=> to convert anything accepted elsewhere in geojs to a hex string.

I have been trying to set a custom color for my rectangles in a LegendWidget I am using. I was looking into the provided example code that said that the fillColor could be a string or object. Is there an example of how the fillColor object should be constructed?

Here is some example code of what I’m trying to do:
Note that the uilayer is a reference to a layer that I already made before instantiating the legendWidget.

var legend = uilayer.createWidget('legend', {
    position : {
        bottom : 0,
        right: 0

   name : "Test",
   style: {
     fill : true,
     fillColor: {'r' : 1, 'b' : 1, 'g': 0}
   type : 'rect'

I was under the assumption that the color object would be an rgb object with values 0 to 1 as I have seen in other places in the geo.js code (specifically the geoJson reader)

Any help would be appreciated.
