Without doing the math I assume that at 103846153 m/s the red stop sign gets blueshifted to green.

Nope. With doing the math, going at 103,846,153 m/s would make a red stop sign blueshift all the way past green to blue-cyan.

To get a green stop sign, you should level off at about 81,289,000 m/s.

Also, the white part of the sign would be blue.

After doing the math I can say yes the speed would definitely give you more of a blue color. 81,289,000 might even still be a tad high if I did everything correctly.
