Colors! (Patreon)

I've got a question, "Everything's fine, but I'm not happy with the colors. Don't know, I can't get what I want. Maybe there's some secret way  to improve it?"

No secrets :) I will show what I do. For example, this photo. It's a almost ready, but color is kinda lifeless, I want to add some warm.

First, Saturation. Don't forget about it.  

Second, of course, Levels. Usually, it's about red and green|blue combo. Reduce blue and get more green, vice versa.

Third, Selective Color Tool. I don't use it a lot, but sometimes it's quite helpful if you to improve selected color. 

Fourth, Cross Processing from Color Efex plugin. But, don't forget to play with Levels settings until you merge layers. You can get really good result, just try everything.
