DO NOT USE THIS IN GTA:ONLINE, YOU MIGHT GET BANNED!!!
It works quite well for FiveM though

Anyways,
This is my personal preset that I use for GTA V, and I just felt like sharing it here.

Yes yes, there are almost too many Reshade Presets out there for GTAV, but when making this for myself I tried to keep both realism and colorfulness in mind without oversaturating and overdoing the contrast, while at the same time counteracting a bit of that green-ish grey looking tint that you may or may not have noticed in Vanilla GTAV. I also used Neobloom to add bloom to the headlights and tailights of cars, with the side effect of making some of the UI and brighter parts of the sky glow (Oh well, you can disable this if you want, of course!!!).

Disclaimer: I didn't create any of the shaders used in this Reshade preset
I didn't use any graphics altering mods in the comparison screenshots except for my Reshade Preset toggled on and off.

I'd Highly suggest pairing this with some Graphics Mods like Naturalvision Evolved or Naturalvision Remastered (choose brighter nights if possible!!)

||Install like any other Reshade Preset!!!||
-Go to https://reshade.me to download and install reshade

-Direct it to where your GTAV.exe is located (the location can be found by right clicking GTAV in Steam and going to Properties>files>Browse local files and it'll be there)

-MAKE SURE YOU INSTALLED ALL THE OPTIONAL EFFECTS (except the legacy effects)

-When it's done, it'll say that Reshade is installed and you can close it out

-Afterwards, just drop the Small's Simply Colorful Preset.ini into the same Grand Theft Auto V folder

It can be used in future versions as well,
But for Maximum compatibility, this preset was made on Reshade version 4.9.1
