Simple Watercolor Painting: Mini Nebulas Using a Variegated Wash
Step 2: Let the Colors Blend
Without waiting for your base to dry, mix your Indigo paint with the Permanent Rose still left on your palette, and the result will be a more mauve or violet shade. Lightly brush this violet hue onto the areas where both colors meet, to further highlight the blended area. As you add these colors, you will be using the variegated wash technique (i.e. adding wet paint in wet paint), since your paper is still wet with paint. The result should be a blooming swirl of colors, where the upper and lower parts of your nebula is framing the middle with dark Indigo.
You can continue to add more of the Permanent Rose paint onto the center to make the colors more vibrant. Try to keep your color placement as random as possible as well, so it looks more cloud-like in form. You have to be careful not to overdo the mixing and blending of colors as this will create mud, instead of a natural-looking fusion of hues.
