Unable to use rgba colors in swatches
As of 2.14.0,  swatches will only accept hex values, while previously it worked with any valid value recognized by TinyColor including rbga. This appears to be introduced by #461 

My app uses transparency by default and I want the palette to appear the same as what is the user sees after the selection. 

Would it work to switch components without a manual hex input back to just `tinycolor(color).isValid()`?
