First of all you need to get the latest version of the conky’s from github. That is accomplished by following this tutorial.
Basically we will use the script in ~/.config/openbox/scripts and you will have a backup of the old ~/.config/conky folder.
If we have the very latest version of the conky’s then we will change one conky in particular.
syclo/clock-crimson-bg-topleft.conkyrc will become syclo/clock-orange-bg-topleft.conkyrc.
You have about 16 million colors to choose from. Change the conky to your liking.
