BMW used yellow decades ago as factory color for them as well.
Other brands like Buick have Yellow DRLS.

J578 MAY88: White, white to yellow, white to selective yellow, selective

that the distance from its lighted edge to the optical center of the
nearest turn signal lamp is not less than 100 mm, unless:
(i) The luminous intensity of the DRL is not more than 2,600 candela
at any location in the beam and the turn signal meets the requirements
of S22.214.171.124; or

bus that is manufactured before October 1, 1995, and which uses an upper

not optically combined with any lamps that are required by this
standard, and which are used as DRLs to fulfill the specifications of
S5.5.11(a), shall be mounted at the same height, which shall be not more
than 1.067 m above the road surface measured from the center of the lamp
on the vehicle at curb weight, and shall be symmetrically disposed about
the vertical centerline of the vehicle.
Doesn't matter if they are DRLs or not. If they are a distracting color they are illegal. A yellow like on the ALMS cars MIGHT be able to pass, but it would depend on the officer.
Thats amber not yellow. Look up the legality of colored halos. They are illegal.
