Adding colour to cards
Adding a background colour is an effective way to theme your cards and make it easier to spot patterns.
Choose Colour from the tools at the top of a box or stack.
Choose the colour you would like to use and then click on each card you want the colour to appear on. You can add different colours to different cards, so it's a useful way to pick out cards with different themes.
When you've finished adding colours, click the X to leave colour mode.
If you’ve used a range of different colours you can sort your cards by colour using the Sort option the toolbar above your cards. Find out more here.
