Here is pretty nice-looking and super easy way to customize taglist! The idea is simple - literally write ‘awesomewm’ in the taglist using letters from the awesomewm logo:

To customize the taglist the same way you need to install font which I generated using icomoon.io service from the svg images of letters from the logo. You can get it from my github. And then simply name your tags in rc.lua using this font:

At the beginning I tried to use svg images directly in the tags, but had too many problems trying to align them properly and getting rid of the gap between tags. And for the text names this is done by default.
Another good thing about using font instead of images is that it’s really easy to theme using Beautiful theme library whereas for images you’d need to create several images with the same color (for focus, urgent, etc.). For example in my current configuration I use following colors:

theme.lua

...
theme.taglist_fg_focus    = "#3992af"
theme.taglist_fg_occupied = "#164b5d"
theme.taglist_fg_urgent   = "#ED7572"
theme.taglist_fg_empty    = "#828282"
theme.taglist_spacing     = 2
theme.taglist_font        = "awesomewm 11"
