Yeah. That's true about Graham watercolors -- it doesn't dry out easily in palette. But, for the same reason, it's quite easy to re-wet once it's dry. So, you may pour out fresh paint just like Teoh said (you won't have to pour a lot since it's really concentrated). Or, what you can do is -- try to dry them out completely in palette (which has a lid) beforehand -- pour the paints, keep them directly under some table fan and make sure it's dry (they won't be touch-dry, but just make sure they won't crawl in palette).
