The color picker is invisible behind a mask, e.g. a ScrollView mask

Thanks for the nice color picker.
There is may be a bug, if you use the color picker in a scroll view, it becomes invisible if you deactivate the mask image, the color picker becomes visible again.

I've looked into this and the fix is to replace all .material with .materialForRendering in ColorPicker.cs. The reasoning is that apparently a copy of the material is made when masks are involved, so you need to use .materialForRendering to access the correct shader.
