ok so im currently making a map on paper. and im at the point where i want to start coloring in (with colored pencils) the desert, grasslands, mountains, etc. but i dont know how to blend two opposing colored zones effectively. i want all the coloring to be light so the borders wont be very rigid. but i want them to mesh well nonetheless. i looked around and couldnt find what i needed so i thought id ask for expert advice. any tips would be appreciated
