Scumbling
Scumbling is painting thin layers of opaque light color over dark colors, which gives a broken color effect. Scumbling is rather like glazing, but with light colors over dark. The colors mix optically rather than on the palette, and the result is shimmery, opalescent.

Stippling
Stippling is similar to scumbling but you are adding more texture than contrast. Same strokes of paint but you are working for a texture effect instead of a color effect.

Sponging
Is using a seas spong to create dimensional paint. It is similar to stippling but you are using a thicker surface and creating a more dynamic color and texture effect.
