Hello there!
I recently changed my default Sway colors for those which are based on the EOS branding website link. I tested this on a custom lxqt config with Sway as the WM (and ironically, use about the same RAM usage as the community Sway install of eos).
(On a side note, the TrelliumRC3 lxqt theme fits well with this Sway color theme but you will have to set up your palette manually).
Remember to add a line in your Sway or i3 config file like this:
And create a new .conf file with the data provided in the image (or your own, i won’t judge). 
include path/to/yourswaycolor.conf
Have fun!
