Most of the time my workflow consists in a black window (terminal or text-editor) and a white one (web browser), so any brightness level is either too dim for the dark windows or too shiny for the browser, thus effectively I have to repeatedly
- lower brightness when going from terminal → browser.
- increase brightness when going from browser → terminal.
Clearly this is very frustrating.
I have Redshift running but it does not eliminate the problem.
Using browser extensions to darken webpages turns out not to be an option since many webpages become unreadable.
I have only one monitor, so I cannot keep dark windows in monitor X and bright ones in monitor Y.
Similar question on Ask Ubuntu but no response.
The software would automatically detect if the window is bright or dark and adjust its brightness accordingly, so that it could even deal with a split screen with one bright and one dark window.
The software would operate on individual workspaces, so that I could set higher brightness on a workspace where only dark windows would be spawned; or
The software would scale the RGB components of each screen pixel by a fixed factor, say
#000000(black) would still be black,
#3B3B3B(gray) would be mildly darkened to
#FFFFFF(white) would be harshly darkened to
