This is a technique I use a lot. It involves combining paint colors to give a gradient, or subtle shift, in color across a canvas or paper. Here are some examples of where I have used this technique:
A corner-to-corner, multi-color gradient:
A top-to-bottom, one color (multi tone) gradient:
An inside-to-outside, multi-color gradient
A couple of things to note before we get started.
You don't have to stick with one color, but try to stay on one side of the color wheel. If you try to grade colors on the opposite sides of the color wheel (think purple and yellow) you'll get brown. If you stay with colors that are connected on the color wheel, you'll get a nice shift in tone. In the first picture above I used yellow, orange, and red. In the third, I used yellow, orange, and two different shades of brown.
If you're going to try the technique on paper, you'll need to seal it first, or else the paper will soak up the paint before you can get a nice blend. A single coat of mod-podge is all you need to seal the paper. Just let it dry thoroughly before painting or your paint will crackle (which is another cool technique).
If you are using thick paints (think Ranger's paint daubbers) you'll want to add a little water to your paints first, or else they dry to quickly to get a good blend. Just try to get the paint to the consistency of everyday craft acrylic paint and you should be fine.
I use foam brushes to apply the paint and do the first rough blend (the fat side of a 1-inch foam brush works really well for blending) and drug store makeup sponges and foam brushes to do some of the finer blending.
I usually end up using one foam brush for each color of paint (light, medium, dark) and one for each color transition zone (light/medium, medium/dark). So make sure you have enough brushes before you start.
As the paints get darker in color/tone, use less. Dark color paints will quickly overpower your gradient. In general, I try to work from the lightest color to the darkest color. Sometimes that's not possible, like in the example I give, below.
All right, here we go...I'm doing a one-color (multi-tone), corner to corner, double gradient for this example.
Layout all your paints and brushes/sponges before you get started. You have to work while the paint is wet, so the last thing you want to do is have to run after something. Go ahead and thin your paints with water, if desired, at this stage as well.
Lay on your lightest color first, then add the medium color, leaving a little bit of space between them.
Using a clean foam brush, blend a portion of the medium color into the white space and just a little bit of the lightest color, using a circular motion.
Next, blend more of the medium color into the first color blend. This starts creating a gradient of color.
Now go back and blend a little more of the light color into the first color blend (using a clean side of your foam brush or the brush you used to apply the light color in the first place).
Once you get these rough blends done, you can go back and blend the transitions between them with either a foam brush or a makeup sponge.
Keep blending until you're happy with the way the paint grades. Now add the darkest color (use a new brush), again with a little bit of white space between it and the color blend you've already done.
In this case, since I am doing a double, corner-to-corner gradient, I am leaving some of the dark colored paint unblended for the next step.
Now I'm going to blend from dark to light in the opposite corner. The technique is the same. First, lay down the medium color with a little white space between it and the dark color.
Blend as above, pulling the dark color into the white space first and then blending with the medium color.
Keep blending while the paint is wet. As the paint dries, you start to get interesting effects as you blend. Keep working the paint until you're happy with it. Once you're done, use your paint-loaded brushes to paint the edges of the canvas in similar tones to the canvas.
Here's my finished canvas!
Give my hubby a hand for taking the photos for this technique, or else I'd have one paint covered camera! Happy Wednesday!
