NetLogo: Moving turtles towards patch color

Is it possible to have a turtle move towards a patch with a certain color?

i.e. have a turtle move towards red patch from blue patch?

sure enough

ask the turtles in question to

face one-of patches with [pcolor = red]
fd 1

although you should do some exception handling because if there is not a patch of that color you will get a

"FACE expected input to be an agent but got NOBODY instead. error while turtle 0 running FACE called by Agent Monitor"

error

I do it something like this

 let targ one-of patches with[pcolor = red]
 if targ != nobody [set heading towards targ fd 1]

I hope that works for what you want.

Alternately as I was reminded in the comments.

If any? Patches with[ pcolor = red]
[set heading towards one-of patches with[ pcolor = red ] fd 1]

But as Seth says in the comments that computes the red patches twice which is costly.
