NOTE: As Nova 5 and above includes a native colour picker, this extension will not receive further updates.
The Colour Picker Nova extension allows you to insert colours into your HTML, CSS, and Javascript files using the default macOS colour selection dialog.
Use the Choose Colour (⌘*) right-click command to choose a colour and insert it into the text.
If a colour is selected, the picker shows the existing colour, and overwrites it using the same format. Otherwise, the format is determined by the Default Colour Format preferences item.
By default, hex colours are generated in lowercase. Select the Capitalise generated hex codes preference to modify this.
This extension is implemented using JXA and the osxascript process. Accordingly, modification of alpha channels is not supported.
