What is SpaceFN and why you should give it a try
The SpaceFN concept - setting up your space key as a layer switch when held - is probably one of the most useful tweaks in the keyboard hobby. Let me explain how it works. My SpaceFN article on kbd.news made some rounds recently - quite surprisingly given the age of this concept. This piece you're reading is a condensed version of the full post. If you're left with unanswered questions, you'll most likely find the info you're looking for in the original write-up. On my imaginary top list of the most useful keyboard features, tweaks and hacks, SpaceFN would deserve a podium finish for sure. But what makes it so special? In short: SpaceFN is easy to implement, easy to learn, costs nothing, can be used with any keyboard, and can improve your productivity instantly. I will list its benefits below, but can state right at this point that the SpaceFN concept, setting up your space key as a layer switch when held, is clearly one of the most useful tweaks in the keyboard hobby....

How to replicate: In LED edit mode set every switch in a row to the white color. Next, in a different row that is completely blank set four switches right next to each other to the white color. This incomplete row will have a pinkish white color compared to the bluish white color of the fully on row. For extra fun, set more switches in the incomplete row and watch the white switches change color slightly.
The other issue that you're reporting is color bleed, which is more of a design issue than anything else. There will be slight color shift as you set more LEDs. That's not electrical or firmware, that's optical.
I'll work on an updated firmware and communicate when it is available, thanks again!
