As always happens here in Brazil, we can’t buy a lot of things, by many causes, as distance, that brings elevated costs…
So, to do the vision tetra we don’t know how to buy the green plastic.
If someone could help us, please just identify the color to us. So we can do a paint or something for simulate the vision tetra… :rolleyes:
p.s.: if the color is one of the colors in chiefdelphi, please write a word with that color… Thanks! 
We used wood for ours and the painted it with the specific green spray paint. I’m sorry, but i don’t know the exact name.
The color of all the Targets is located at: http://www2.usfirst.org/2005comp/2005_Target_Paint_Colors.PDF
Good Luck
The “official” tetras are also painted wood. Check out the FIRST Documentation section of the website for the exact building specs.
Thank you!! and if i’m not asking too much, anyone knows the measures of the targets on that stay the ground? (under the goals and the red and blue ones)
The official field element vision tetras that will be used by first at regionals and the championship event are not painted wood. They are made of 1/4" of HDPE with an adhesive bright green vinyl sheet that will be on the outer face of the HDPE.
You can find this HERE
All the colored targets on the ground are 36" on a side.
For reference this is in section 3.2.2
“A vision system target is located in the center of the base of each Goal. The
vision system goal is constructed of a triangular piece of yellow 1/8” HDPE
on the floor, with each side of the triangle three feet in length. The vision
system target is centered within the base of the Goal.”
