Bug

What is the current behavior?

When enter a color name like red or green in input field no matter of the current selected mode, it seems to shortly convert to the hexa code for red, but then revert to orginal selected color hexa code. In the preview the round circle has however been updated.

If the current behavior is a bug, please provide the steps to reproduce and create a JSFiddle.

Can be reproduced in the default template or the demo page.

What is the expected behavior?

By enter e.g. red it is great if change to the hexa color code for red and update the preview as well. However it shouldn't revert back to original selected color code.
It also seems it is flickering a bit when just deleting part of the hexa code.

Off topic: There is a minor typoe here https://github.com/Simonwep/pickr#the-hsvacolor-object should be "Converts the object to a cmyk array" instead of "Converts the object to a cymk array".

Kinda a duplicate of #133, anyway fixed in 973f317 :) It will now convert the color-name to the current representation if the input field get's blurred! Ah yeah, thank's - fixed the typo ^^
