Color-changing modes
The Color Paint and Color Jitter modes, unlike the path editing modes, change the colors of objects instead of their shapes. Yet they share enough common features with the path-changing modes to be part of the same tool: These modes also use a circular soft-edged brush controlled by the Width and Force parameters on the Controls bar and affected by the pen pressure (if you have a pressure-sensitive tablet).
* Color Paint applies the style of the tool to the selectedobjects under the brush. The style of the tool is visible in the style swatch at the rightmost end of the tool's control bar; it can be changed by clicking on the color palette or by any other style assignment command, such as Fill and Stroke dialog. (Note: unlike all other tools, in Tweak tool in Color Paint mode you cannot assign style directly to selected objects; any style-setting command changes the tool's style instead.)
The fill from the tool's style applies to the fills of the paintedobjects, and the stroke applies to the strokes. If the tool's style has no fill or no stroke, it won't affect fills or strokes, correspondingly. For example, if you want to color the fills of objects blue but leave their strokes untouched, assign blue fill to the tool's style (just click blue on the palette) but set its stroke to None (middle-click the Stroke swatch in the statusbar). Similarly, master opacity in the tool's style
This mode allows you to literally paint over objects, shiftingtheir colors towards the target style of the tool. For example, if you paint with yellow fill over a blue-filled object, the object will become greenish blue, then green, then yellowish green, and end up being exactly the green color you're painting with. This speed of this gradual transition depends on the Force and pen pressure; also, objects touched by the periphery of the brush are less affected than those hit by the brush center. Overall, using this tool is very similar to a soft brush in a raster editor such as Gimp or Photoshop.
This tool is great!... BUT ;) it think it should be more gradually sensible to the force parameter: even at very low forces, I very quickly arrive to the end color. At high sensibilities, I virtually never see the intermediate colors. From your explanation I had the impression that force and pen pressure where two possibilities for sensibility. maybe with a pen you can achieve "graduality" at high forces using very light pressures? Wouldn't it be simpler if, when pen pressure is enabled, the force field was greyed out and the 0-100 scale was determined by pen pressure? (or maybe it's already the case, I can't test unfortunately).
* Color Jitter mode does not apply any color, but instead jitters(randomizes) the colors of the objects it touches. The force of the action determines how strong is the randomization, i.e. how far the colors deviate from the original values. This mode does not use the tool's style.
Here again, as soon as the force field is >20 the color jitter is so strong that I can't really predict the result and the usability of the tool is therefore limited. Could it be made more gradually sensible?
Since the tool's style in the tweak tool can only be set in the color paint mode, could it be made N/A in other modes. The fact of having it up there drove me to try to apply a style and this changed the style of the objects on canvas rather than the tool's style (this was before reading your explanations but well, it's even better if things are instinctive, doesn't it?)
Thanks again for this, it's awesome. PS: it is in the newer mac dev build for those interested, along with some dockable dialogs.
