I have a Centos 7 install that seems to be filling up disk space to 100% on
the root partition.

in /tmp I found files of names...
systemd-private-XXXXXXXX-colord and rtkit
I have never seen these files before.

there were also files of XXXXXXXXXXXXX.tmp    in the /tmp folder.

Why are these files appearing? I have a number of installs and never came
across this before.
