Get color value from backdrop?

Hi,

I have a top-down game project where I'm trying to change max speed of an object according to what surface the object is travelling on.
I would like to achieve this by reading a backdrop pixel colour below the object. Is this possible somehow?

I'm all ears for better solutions to achieve the same result. Help would be greatly appreciated.

Thanks!

Thank you for your replies!

To minimize speed and world building issues I am trying to avoid using separate objects for terrain types because I have a huge world map with complex shapes.
That is why I had this theory that I could turn the situation around and make the actual moving object to work as terrain sniffer. This logic would allow me to save ton of work and CPU resources in the long run.
The whole project is designed graphically to support this kind of method. Roads are 1 color, forests are combination of only 3 colors and so on.

Seems like there is no solution yet that I'm aware of. I tried experimenting with "Get Pixel Color" object but the results were not very promising.
