Hybrid was only basic color grading support, so I would in general recommend to use i.e. DaVinci Resolve so the color grading there and export the grading as a LUT (.cube) and then use it in Hybrid through Filtering->Vapoursynth->Color->Matrix->TimeCube.

That said, Hybrid also comes with a bunch of LUTs, if you enable "Filtering->Vapoursynth->Color->Matrix->TimeCube->Custom LUT folder" and select the 'color'- folder (Hybrid\64bit\vsfilters\ColorFilter\TimeCube\color), maybe one of these already does what you aim for.

Additionally, you can use the filters under "Filtering->Vapoursynth->Color" especially Basic and Misc to do simple colro grading.
(side note: you might want to enable "Filtering->Vapoursynth->Misc->Preview->Histrogram" for the Vapoursynth Preview)

Ps.: one can also use custom code like the one below to lessen highlights:

## LESSEN HIGHLIGHTS
clip = core.std.Expr(clip, expr=["x 200 > x 0.8 * 40 + x ?"]) # alll color plaes
clip = core.std.Expr(clip, expr=["x 200 > x 0.8 * 40 + x ?","", ""]) # luma only

The problem with these multiple halos that if you filter to aggressively the scene with the other guy in the clip will be too smooth.
So if you have the time:
a. apply different dehalo values on different ranges of the clip
b. maybe even try to limit the dehalo effect with some addition edge masking
