This video shows an easy way to change the color of your landscape during runtime via a scalar in a Material Parameter Collection. I had a frustrating time trying to change the color by getting a reference to my landscape material and changing the scalar parameter, it just was not working even though I was changing the scalar the material was not responding, until I used a Material Parameter Collection. This may be obvious to people with experience working with materials, but I could not find anything on this, so I made a video.
