|
| Increase contrast, a lot, in the original RGB space, then
| only keep the R channel, then invert the picture.
|
| It's like doing a "black and white" mode, but as "black and
| red" and avoids losing "faint colors".
|
| Also, you remove the color consistency problem (IIRC the
| perception of colors is not symmetrical on light and dark
| backgrounds, I think it was pioneered by Ethan Schoonover
| for Solarized)
|
| BTW the inversion should be optional, to be nice to apps
| using a dark theme (ex: many terminals by default) and may
| work best on a window-by-window basis if that's possible on
| the Mac.
|
| The best results are when using a system light theme +
| light themed apps.

| Very nice! On windows, I use a program that runs matrix
| operations on the color space, so that I could increase the
| contrast, invert, then only keep the red chanel
|
| On wayland I can do that with wl-gamma: for an equivalent of

| busctl --user -- set-property rs.wl-gammarelay /
| rs.wl.gammarelay Temperature q 1000`
|

|
| I had similar setups for my editors, but removing syntax

| channel turned out to be simpler to generalize

| There are some cool research papers about delayed

| that every 10 seconds or so.
|
| Then later you upload all the collected data to a big cloud

|
| People are using that technique to have GPS trackers with
