Gradient from distance (walkscore)

Hello friends

I’m a beginner in Grasshopper and I need to present my post graduate work in the next week. I would like to do something close to this Walkscore example:

In the file below, I identified a radius of 400m. I would like that the farther from this radius, the darker. I need some help, please!

Hi,

Simply try measuring distances from your origin points, either use dynamic or fixed bounds.

It’s fun.
