Introducing User Defined Brushes, and Gradient Color Animation.
In this video, the User Defined Brushes were used to draw the flowers and grass before Shadowed Strokes setting was turned on. You notice that the flowers/grass is rather dense. If you turn on the Shadowed Strokes before drawing with the User Defined Brushes, then the marks you make will be less dense, because drawing with shadows takes more time. But that may be exactly what you want: a texture that is less dense, and the ability to better control and see the individual marks with the help of the shadows.
Note that Gradient Colors work only with objects that are "filled" with color by TwoToJazz. For example the two-finger calligraphy brush used in this video to write the word Hello creates an object that is filled with color. The free-style brush used to draw the flower is another example. In contrast, there are brushes in TwoToJazz (like the one used to create the grass) that draw only lines that could be thin or think, but have no filled area. Line-based objects do change colors during color animation, but with no gradient effect. The brush on the bottom of the one-finger menu is also a simple line brush with no fill and thus does not show the gradient effect.
Using the free-hand drawing tool of TwoToJazz an image of Beethoven is colored using thin (low opacity) colors. The drawing was then Color Animated in TwoToJazz and snapshots of it were saved. A selection of the snapshots were used to create a collage (using PhotoGrid app), and then the gris was further processed using Waterlogue app. All images were then put together in a final grid.
Some useful tips:
Try coloring your image with thin (low opacity) grayish colors, using the free-hand drawing tool. When animated in TwoToJazz grayish colors (colors mixed with both white and black) generate many different colors. More pure colors in contrast generate colors that are more similar to the original color.
Color Animation is the latest of unique features of TwoToJazz, introduced in version 1.3. This feature is made available when both "Mix Color" and "Advanced Edit and Animate Tools" are unlocked. To enable this option, in Settings menu turn the "Animate Colors" switch on. Now, when you activate the Animate mode, the objects don't move, but their colors change, and you can save snapshots of the color variations into your camera roll by pressing the Save button. If you have replicated objects in your drawing, each replica will have its own color variations.
