The Colour Replacement Brush Tool works by replacing the colour of pixels on the current layer with the Foreground colour selected on the Colour Studio.
The pixels affected by the Colour Replacement Brush are determined by the following:
The colour of the pixel under the tool when you tap on your page.
Whether the pixels are within the same selection area.
The pixels are included in the painted stroke.
The tool's Tolerance settings (see below).
Settings
The following settings can be adjusted from the context toolbar:
Width—the brush (stroke) size in pixels.
Opacity—how see through the brush is.
Flow—how fast the brush effect is applied (1% is very slow, 100% is immediate).
Hardness—how hard the edges of the brush are. The brush appears softer as the percentage decreases.
More—tap to display the Brushes dialog to access advanced brush settings.
Colour—displays a pop-up menu for selection of a brush stroke colour.
Tolerance—sets the range of pixels affected when a pixel is tapped. For lower tolerance settings, pixels must be very close in value to the tapped pixel. For higher tolerance settings, pixel colour can vary widely from the tapped pixel.
Continuous—if this option is off (default), the initial tapped position determines the reference colour to be replaced. When selected, new reference colours are determined as the cursor moves.
Contiguous—when selected (default), only adjacent qualifying pixels under the stroke are recoloured. If this option is off, all qualifying pixels under the stroke are recoloured, even if they are non-adjacent.
Force Pressure—Toggle to control brush size with pressure if using a pressure-sensitive device. This overrides brush defaults.
