Convert a design to monochrome while maintaining full control over how individual colours are converted.
Settings
Apply this adjustment via the Adjustments panel using the following settings:
The options control the lightness value of the named colour areas of the design. Drag to the left to darken areas of the named colour, drag to the right to lighten them.
You can also drag on the canvas to target and modify a colour tone. The initial pressure on the canvas will identify the predominant colour; dragging left will darken areas of the identified colour while dragging right will lighten them. The corresponding option will be updated.
