Two different colour palettes on Mac numbers

When changing the color of text in a Numbers Spreadsheet, when I click on "Text Color" in the Format/text tab, for years I have always seen this selection of colors appear in a color palette:

After some software version update recently, the colors have changed to this dreadful selection of dull colors:

About half my spreadsheets have the first set of color selections and the other half have the 2nd set of color selections. Why is this? And how can I get the first set of color selections (above) to appear on all of my spreadsheets?

NOTE: I understand that I can click on the color wheel which will pop up a separate window that I then need to look for somewhere on my displays and select a color from that window, etc., ... but I don't want to go through 2 or three extra clicks every time I want to select a text color. I want to keep the original selection of colors, as show in the first color selection above.
