Numbers - Reset to Default Colour Palette
I have a series of matching spreadsheets, but one of them has a muted palette of colours compared to the rest. I'd like it to match the brighter colour palette on the rest of the spreadsheets, which is also the default colour palette I get when I create a new document.
I'm not sure why this one spreadsheet has muted colours - I've never intentionally changed to custom colours - but I wonder if it might have been caused by combining it with an Excel spreadsheet at some point in its history - perhaps the colours are default in Excel? Or perhaps it's related to an older version of Numbers and a software update. I think it is an older spreadsheet than the others.
Everything appears to match in terms of settings, except for the actual colours. I can see the colours are definitely different because they have different HEX numbers etc when I look in the Colour Fill dialogue.
In my spreadsheets, individual cells are coloured in a complex system denoting different stages in tasks, so I can't easily start again in a new document. Also, if I copy and paste the muted spreadsheet content into a new document, I find it also copies the muted colour palette.
How do I make the muted colour palette match the brighter default colour palette? Is there a preference somewhere that I can just reset?
