Here is a solution for LuaLaTeX or XeLaTeX:



\[ \redtriangleup\redtriangledown \]

New Computer Modern sample

In PDFTeX, load \usepackage{stix} or \usepackage{stix2} instead of \usepackage{newcomputermodern}.

ETA: You can replace \bigblacktriangleup with \blacktriangleup and \bigblacktriangledown with \blacktriangledown as in needle’s answer, while using the same approach. Many more packages support these commands.
