I was working on a newer 1-bit mockup last night (kind of a start up screen or something).
Previously, I have thought about using post visual effects like chromatic abrasion (or something else with offset color channels) as well as trying to replace the black background with something high res, like a smooth gradient possibly with minimal texture, and turning all black to alpha, or maybe even a glow similar to a CRT screen or something. Unfortunately, I never got around to experimenting with that. Though I did take in Eigen's
advice and try something other than black, and I got something that still feels very clean and wouldn't require such complicated post-effects. Here's a few variants.
(I'll be trying many more colors later, and probably darker colors as well)
I'm thinking that these colors could change depending on what area in the world it is, but never more than two colors in the same screen or location. I don't know if I'll stick with these bright colors, but I'm sure it would look pretty good with dark shades of saturated color.
I might also try some of my old ideas in the future.
