Thanks, see some comments below.

This is too long for a NEWS entry for such a minor feature. Please make it
shorter. Just saying that some fields of Proced display will be shown in
distinct colors, and mentioning the new defcustom to turn that on, should be
enough.

Our style is to avoid passive tense whenever possible:
Non-nil means Proced should display some process attributes with color.
> +(defcustom proced-medium-memory-usage-threshold 0.5

It is better to avoid such constructs. Instead, say this:
The upper bound for medium memory usage, relative to total memory.
Note that I removed "in bytes", since this is not the units in which this is
measured.

I think "rss" should be in all-caps, as "RSS". Same for "VSIZE".

Is this color visible well on both dark and light backgrounds?

Please mention Proced in all the doc strings of these faces, to make it
clear they are only used by Proced.

^^^
Please use "process ID", not just its abbreviation.
> +(defface proced-pid
> + '((((class color) (min-colors 88)) (:foreground "#5085ef"))
> + (((class color)) (:foreground "blue")))

"Face for process IDs", note the letter-case (here and elsewhere in the
patch).
> +(defface proced-cpu
> + '((((class color) (min-colors 88)) (:foreground "#6d5cc3" :bold t))
> + (t (:bold t)))

"CPU", in caps.
Thanks for working on this.
