Download these free Colorboost Lightroom profiles by VOXCOLOR to make colors pop. They work in a much different way than Lightroom's vibrance or saturation and can give you much better results. For example, with vibrance, neutral-color objects (rocks, roads, and white walls) can turn unnaturally colorful. Colorboost lets you boost colors without this flaw.
This is the first time you can do this in Lightroom. In the past, this could only be done in Photoshop using a technique called Vibrancy Masking. The profiles are compatible with Lightroom CC and Lightroom Classic CC.
Its not really free.. the full product cost money.
