Do you remember when Autodesk Maya went from the old grey color picker to the new Qt one in Maya 2011? So much rage… that tiny window disappearing all the time was kinda frustrating on comparison to the old one.
Well, everybody may already know this but… but if you do a double-click on a color picker button instead of a single-click, it will bring this fantastic and usable window. Enjoy!
More over, if you drag and drop a color picker button, it will open the floating window where you dropped your click.
One last tip for the road, in Maya 2010 you could pick a color outside of Maya very easily, but now the pipette just don’t work outside Maya… in fact it works with a workaround: use the pipette on the Maya UI but don’t release your mouse, then unclick wherever you want outside of Maya and voila!
