Neat. Gives you peninsulas and bays and everything. Here's my result:

I kinda like what converting it to .jpg did around the edges.

First, draw the general shape of the landmass in a colour that's not red or
blue. In a seperate window, make your red/blue "snow" with Adrian's
technique. Paste your third-colour landmass over the snow and fill the mass
with red, then blue ... that should be all it takes; by the third fill I
found it didn't look much like the original shape anymore and backed off
with 'undo'.
Clean up the shape as in steps 7-10 and there's your map.

Here's mine:
