LUT contains command-line tools and Go packages for applying colour adjustments to images using lookup tables. I gave a talk on the subject at London Gophers.
This command-line tool and packages were written to inspect LUT's locally, and provide basic server-side rendering. This is most likely a bad idea, and you should probably be doing colour manipulations in OpenGL or a similar graphics programming framework.
There are tons of free LUT's available online, luthouse.com is a great example.
