Hello, I am new not Kdenlive.

I bought everywhere and did not find anything related. As in other editors (adobe) there is a "adjustment layer" tool that applies a color correction throughout the video. In Kdenlive is there any tool that does this job?

You can add every effect to the track-head (the part on the left of where the time-line starts. It will then work on every clip you placed on that track. Look in effects under colour and try to find the one you want to use.
