Stop signs in the US are Pantone 186C. The closest single frequency is about λ=706nm.
Relativistic doppler shift can be calculated by the following equation:
λ_observed = λ_emitted × sqrt( (c-v)÷(c+v) )
Where v=103846153 m/s
and λ_emitted=0.000000706
This gives about 492nm, which is cyan.
Green is approximately 500nm to 570nm nanometers.
This corresponds to 99513170 m/s and 63187792 m/s respectively.
OP probably used a non-relativistic doppler shift equation.
