I too wanted to modify the default template for the color-picker. The template for Kendo UI Web v2013.3.1119 is on line 23760
It does not appear that _template is accessible, so I overwrote this with my own template. I would prefer not to do this, because it makes it an issue when upgrading Kendo UI.
Can this be exposed so on initialization we can set the template as we do with other kendo controls?
