Wetblending all the way.
I know everyone says this is hard, but there\'s blessed little challenge to it; it\'s just one of those things that has a \"trick\". Once you get the trick, you have the technique. In wetblending\'s case, the trick is water. Lots of it. If you\'re trying to wetblend, you need way more water than seems reasonable. When you\'re thinning your paints, add your normal amount of water (I usually use 1 brush of paint : 1 brush of water unless the paint is brand new) then add at least one more brush of water. Since wetblending makes a nice, multitonal transition from your highlight to your shade, it generally makes sense to use your darkest shade and your lightest highlight. This doesn\'t always apply (for instance, a blend from red to green), but in those cases, the blend is generally for aesthetic value anyway. Lay down a strip of your highlight on the highest point and your shade right next to it. Make sure they\'re touching as the colours will begin to twist into each other (assuming your paint is thin enough). Use your brush to swirl the colours together so they have a nice smooth transition. This takes practice, so don\'t worry if it doesn\'t look exactly right on the first go. Blends also require lots of coats to look good an vibrant, so be prepared to repeat this process several times. Good luck!
