Hi Debbie.
Were going to paint Hunter Sky Blue and Midnight Blue (Half/half) using the paints that they use on cars (From a car store)
They have a slight sparkle to them, so you could use them.
If you want your robot to be really visible, then you should get some LED lights and put them on the robot, as they will really make it visible.
Good idea with staying with the theme with robot names, Team Devil-Little Devil and Devils Little Helper.
That way people know that its your robot.
For example, Team Shock named all thier bots after nateral disasters, and Team Hunt (Me) Hunter and our next feather will be called Hunting Dogs (Cluster bot)
Hope that this helps.
Matt
Team Hunt
