How to change colors through the RGB value in the image?

[Emerson A. Cararo]

Hello friends.

How do I change the colors of an image using the RGB code from a color palette?

For example: I photographed an urban scene where I want to use a specific cinematic color palette.

Is it possible to pick colors accurately in HSL?

Thanks!

The way this is usually done is by creating a profile that contains a LUT. https://glyndewis.com/blog/luts-in-lightroom
