The hardest part of using reshade IS what color configuration you want to use. As a few simmers above have stated, we all have our own preferences or look we prefer for the sims. Colors we enjoy or saturation levels desired.
There are a multitude of looks you can give the Sims 4 with reshade as shown here and honestly just choosing one can be hard.

Hence why noblu can just be as easily a solution - although I'd prefer Maxis actually give players the choice in-game to toggle the blue filter.
