RWBY Ultimate character quiz

To change the background colours, select the cell you want in 'Quiz Design', then click on 'Manual', 'Edit Styles' and select 'Edit Styles for: 'This Cell'. Tick the 'BG Color' box, then click in the rectangle that appears and a colour palate should pop up for you to choose from. You can do the same for text colour etc.

To insert extra columns, just select 'Columns: 'Insert After', to the right of screen, then click 'Go'. If you want to insert a gap between the columns, do the same with 'Blocks: 'Insert After'.

'Row: Insert After' will obviously add more rows going down, and these rows can be re-purposed as gaps if you make their border white.
