How to manipulate colours seen?

Recommended Posts

Hello community!

I actually would like to develop a small piece of software that alters colours seen on the monitor. I know about applications like Flux, that remove blue hues depending on time and plenty other stuff.

What I precisely want: Be able to filter out complete or partial ranges and convert them into other ranges. E.g. mapping green colours to red ones. Probably using some matrix to convert them.

So, I'm more curious about how manipulate/access the screen-colours. For example, I'm assuming I will depend on graphics drivers? Or can I bypass graphics drivers by post-processing as I would prefer to be independent of the sheer amount of different drivers.

Especially uncertain about what problems I will be facing... graphics drivers, OS, ... and what programming languages already offer solutions.

Thanks for your time, please note if I've been unclear.
