No, just the color picker in the top left. The RGB on the spheres was before I built the html with color picker.

This is the code that ended up working for me:
```
function hex2rgb(hex, opacity) {
        var h=hex.replace('#', '');
        h =  h.match(new RegExp('(.{'+h.length/3+'})', 'g'));

        for(var i=0; i<h.length; i++)
            h = parseInt(h.length==1? h+h:h, 16);

        if (typeof opacity != 'undefined')  h.push(opacity);

        return 'rgba('+h.join(',')+')';
}
```

I found a shorter snippet that works perfectly:
```
app.ExternalInterface.hexToRgb = function(hex) {
  return ['0x' + hex[1] + hex[2] | 0, '0x' + hex[3] + hex[4] | 0, '0x' + hex[5] + hex[6] | 0];
}
```
Edit: Need to check more.

I put in 181 38 124 and it works fine. Yours didn’t work since it is expecting 255 255 255.

Good catch thank you I missed that. Usually the case for normal maps as well. Yeah I have a list of things I’d like to do including an actual UI.

It seems like the moment I put a math node into the equation to try to convert to linear, it all goes grey whether in Blender or puzzles.

It’s not all perfect yet as I have to account for the fact that the environment color and spot light is going to influence the result. I’m totally open to playing with your solution as well and appreciate you sharing.

Replied there. Big thanks for your input.

Here’s a link to the current working project:

Edit: Click on the sphere’s to set the values, then click the keys to change them.

Thanks for the reply Gliftek. No offense taken, I’ve been doing computer graphics for many years but you’re right this (WebGL) is new to me. I did solve the RGB thing, I’m not sure how efficient it is but it works.

I am using vertex color to drive color so that the user can choose to color each element separately. I don’t think that would be very efficient with materials.

Edit: In Blender that was Gamma 2.2. Changed here to test.

Thanks so much for the project that I can dissect. Based on your conversation with Gliftek, this is as far as I got but the objects were turning black. I think I understand now.
```
        app.ExternalInterface.setKeyCol = function(changeObject, changeColor) {
            var myObj = app.scene.getObjectByName(changeObject);
            var setcolor = changeColor;
            var attrName = myObj.material.nodeVCAliases['Keys'];
            if (attrName !== undefined) {
            var vertColor = myObj.geometry.attributes[attrName];
            }
            for (var i = 0; i < vertColor.count; i++) {
                vertColor.setXYZ(i, 'setColor');
            }
            vertColor.needsUpdate = true;
        }
```

What would the whole script look like if you were setting a vertex colour for a picked object in a vertex colour index called KeyCol? Say I want to do another and call it something else?

Edit: I’d also like user to specify a colour to change to.

Edit2: Would this puzzle work or is it better to set variable and the external js will pick it up? There are two vertex colors: KeyCol and Legend

Thanks! It works kinda but doesn’t reflect what I’m seeing in Blender or using the same values in separate shaders.

The moment I add this to my js file it kills the app and it won’t load anymore. Can someone provide an updated example of a video material?

Verge3d devs, it would be prudent to have this as an example project included with Verge3d or a puzzle to plug videos in to the application.
