DONE headlines take a different color

[Giovanni Gigante]

As per the subject: TODO states mantain the headline color (as expected), but DONE states change it (not expected). As shown in lines 2, 5, 8, 11, 14 of the following screenshot (emacs 27.2 on MacOS launched with -q,  org mode 9.4.4): In the past this did not happen; I have verified this with an ancient installation.
