My histogram is blank when I try to adjust colors on lever histogram and whatever I do colors dont change. Please help.
Which specific version of HitFilm Express are you using?
Are you applying the effect directly to a clip, or to a grade layer?
There's a random bug I've seen where occasionally an effect won't work right away until you switch to a new tab (another comp, or the main Editor), then back again. Give that a try.
