It was around the previous wallpaper bundled with Plasma 5, Graphite, that I began using my wallpapers on all my devices as a form of dogfooding. If I didn't like any aspect of my wallpapers, I would need to live with them for 3 months as a driver for quality.
This is the first wallpaper where I had something that bothered me, which was the blue light. I didn't really like it when I made it, and I should have done something more. For 3 months I looked at the blue section and *hated* it with a passion that I hadn't done more. It used it on my work computer, home computer, phone, everything. Now when I make wallpapers, the Skylight wallpaper is the reminder that I can't leave out one detail - lest I stare at it for months.
