Continuously changing the color of an object on canvas

Question

To continuously change the color of an object, you may use the Fill and Stroke dialog and drag in its bands or color wheel.

Is it possible to do it directly on the canvas, without any dialog?

Answer 1

Yes, it is possible, albeit only in the HSL color model:

1. Select an object.

2. Drag an (invisible) line (a ray, radius) from the actual fill or stroke color into canvas.

3. Then – still with left mouse button pressed – change the angle of this invisible line.

4. Finally, if you are satisfied with the new color, release the mouse button:

 

 

This method will change the hue of the object(s). To change

• saturation (the pureness of the color), press and hold the Shift key,

• lightness, press and hold the Ctrl key.

• alpha channel (transparency), press and hold the Alt key.

You may release and press these modifier keys repeatedly during this procedure to switch among these 4 modes (hue, saturation, lightness, alpha).
