HOW TO Create a spot colour effect

1 Spot colour

To create a classic ‘spot colour effect’, we need to create a black-and-white shot that only features one coloured object. Fortunately Pixelmator Pro’s slider and brush-based tools can target colours with precision.

2 Reduce saturation

Open an image that features a strongly coloured subject such as our iconic London bus. In the Selective Color panel click all the swatches apart from the red and orange ones and reduce their Saturation to –100%.

3 Selective removal

We now have a monochrome shot with only red colours remaining. To selectively remove remaining reds from other objects click on the Desaturate tool. Tick All. Set Strength to 100%. Spray over unwanted areas of red.
