I need some help with kerning my wordmark. I have read some blog posts, and tried an online game to "test" my kerning skills. I usually get a score of 80% or higher, but I also sometimes get a really poor score. Since it's possible to get a score of 100% in the "kerning game", it got me thinking. Is there something called perfect kerning? Any help on improving my current kerning attempt (as well as my kerning process) is appreciated.
Background
This is somewhat a follow up question to one I made a couple of weeks ago, Critique request: Logo design for a tech company.
I went back to the drawing board, asked for help and feedback on The Looking Glass, and ended up with a wordmark and logo I am satisfied with.
Below is my current work in colors, black, and white.
Is it just me, or does the space between "R" and "E" seem shorter on the black background version? I checked to confirm that the space between characters are the same on each version.
Kerning process
My process to kerning so far has mainly been to get the white space between each character to be roughly the same. I started looking at the space between [ITE]. The white space between these two characters are equal, and I used that as a standing point for the rest of my kerning process. The next thing I did was look at the space between [REI] and [ECH] separately. I also tried looking at the wordmark upside down and from farther away.
Maybe the space between the "R" and the "E" could be slightly larger? However, the wordmark looks a bit odd to me if I increase the space between those two letters. Maybe that's because I have been staring at the same wordmark for weeks now.
Here is an illustration of the wordmark upside down with white space in different colors.
