whether there who have managed to change colors, hdr, the fov, ect with good matches, not just change the motion blur, I'm a fan (with photos if possible)

Available options for Colour Correction,
r_ColorGrading=(0,1,2)

My preference for HDR,
r_HDRBloomMul=0.5
r_HDRBrightLevel=0.5

For FOV,
Don't change the cl_fov=55,
Just change r_DrawNearFoV=55 to something like 70 will do.

Put all these commands in an autoexec.cfg & you're good to go. All the Best!
