Project mention: Seeking advice on monetizing an open-source Golang-based video transcoding project developed during university | /r/golang | 2023-06-04

There are a number of projects using manipulation libraries like https://github.com/disintegration/imaging which is already MIT licensed, and then there are various transcoders which I am unfamiliar with, but you will want to consider if you add enough value to make use of those unimportant to the decision to pay.

gnome-gamma-tool

5 86 3.7 Python

A command-line tool that lets you change gamma in GNOME and Cinnamon (with Wayland). You can also adjust contrast and brightness. It works by creating a color profile with the VCGT table, so that changes are persistent and don't interfere with other settings like night light.

Project mention: Tune your low quality display by reducing gamma | /r/thinkpad | 2023-09-10

I purchased a mint condition T490 recently but I found the display to be inferior compared to the touchscreen of my T460. Both have 45% NTSC coverage but the T460 is pretty good in my opinion while I thought the T490 is too bright, almost washed out (it came with the standard FHD IPS AUO panel). Then I realized that it's actually the gamma that is too much for my liking and this is something that you can control from software. So I set it to 90% with this tool and voilá the display now has more contrast and looks much better to me. Difference is pretty big actually, it went from I want to replace it to it's perfectly fine in a blink of an eye. Absolutely recommended!

xcalib

2 66 5.8 C

wl-gammactl

6 43 0.0 C

Project mention: Actually Portable Vim (With a Cute Vimrc) | news.ycombinator.com | 2023-12-25

I don't know what you mean by color management - is it the calibration of the display with xrite/argyll?
For ICC profiles colormgr can help: https://wiki.archlinux.org/title/ICC_profiles#Wayland
If you just need basic brightness, contrast and gamma, wl-gammactl should do that: https://github.com/mischw/wl-gammactl
BTW Hyprland is not required, it's just the most practical way to have shortcuts key mappings in Wayland
