After I made my current avatar I got the idea of doing a signature like it, and if you haven't noticed anything special I'll explain it to you. The concept behind both my avatar and this WIP signature is that what you see will be different depending on what site skin you have on: Reach dark or Light. due to some reasons I can only make it work with two skins so those are what I chose, they have a good contrast in their color and seem popular enough. So, if you look at this with the reach dark skin on it will tell say reach dark skin , if you have the light skin on it will say light skin *note that this is just a WIP and a test to see how many people like the concept, the final sig will most likely actually be way different and wont tell you what skin you have on. Ps. if you have just normal dark skin on you can see what it really looks like.
The coloring of the text. Change your skin to normal dark to see what I mean, its really the easiest way for you to figure it out, its nothing really complicated though.
